Terms of Service

Effective date: 1 August 2026 · Version 2.2

These Terms are the agreement between you and APERTURESyndicate OÜ. They explain what we provide, what we expect from you, what you can expect from us, and what happens when something goes wrong. Please read them — they are binding once you create an account or use any of our services.

We write these documents in good faith and keep them accurate to how the platform actually works. They have not yet been reviewed by qualified Estonian legal counsel.

1. Who we are and what these Terms cover

APERTURESyndicate is operated by APERTURESyndicate OÜ, a Osaühing (private limited company) registered in the Republic of Estonia (EU) under registry code 17384111, VAT number EE102972654, with its registered office at Priisle tee 8, Lasnamäe linnaosa, Tallinn, Harju maakond, 13914, Estonia. Full registration details are on the Company Registration & Imprint page.

In these Terms, "we", "us" and "our" mean APERTURESyndicate OÜ. "You" means the person using our services. "Services" means everything listed in Section 2, together with our websites, applications, APIs, and desktop and mobile clients.

These Terms apply from the moment you create an account or otherwise use the Services. If you do not agree with them, do not use the Services.

If you are using the Services as a consumer — that is, for purposes outside your trade, business, craft or profession — you have rights under EU and Estonian consumer law that cannot be signed away. Nothing in these Terms removes or limits those rights, and where these Terms conflict with them, the law wins.

2. The Services

APERTURESyndicate is a single account across a set of connected products. The Services currently include:

Service	What it is
APERTURESyndicate account (SSO)	One account and sign-in across everything below, including two-factor authentication and session management.
aperturesyndicate.com	The main site: profiles, projects, news, and account settings.
Resonance	Music streaming for listeners, and publishing and royalty tools for creators.
ASAI	AI assistant, chat, roleplay, code and image generation.
ASInstaller	The desktop launcher: it installs, updates and removes our desktop applications on your computer.
ETHERANE	AI platform and the datasets marketplace.
ASVentor	Media tools — conversion, editing, upscaling and the downloader.
ASMusic	Music distribution and release management.
SYNX	The SYNX configuration format: playground, registry and documentation.
Support	Support requests: you open a request from your account, we reply, and the conversation stays attached to your account.
Creator portal	Applying as a creator, the publishing studios, and creator analytics and payouts, at https://creators.aperturesyndicate.com.
Developer portal	API access, API keys, OAuth clients and developer documentation, at https://dev.aperturesyndicate.com.
Subscriptions	One place to see, change and cancel every paid plan you hold with us, at https://subscriptions.aperturesyndicate.com.
Lysicon Quanture (LQ)	Market and analytics publication, operated as a partner product.
Documentation	This documentation site, at docs.aperturesyndicate.com.

We add, change, rename and retire products over time. Section 14 explains how we handle changes, and Section 17 explains how we change these Terms.

Some Services have their own additional terms. Section 3 explains how they fit together and, importantly, that you accept them by accepting these Terms — there is no separate signature for each product.

3. How our documents fit together

One agreement, one acceptance

Accepting these Terms accepts the product terms with them. When you create an account, you enter into a single agreement covering every Service listed in Section 2. You do not sign each product document separately, and we do not ask you to click through a new agreement the first time you open a product.

The documents that come with these Terms are:

Document	Applies to
Resonance Terms of Service	Listening, playlists, the locker, the catalogue API
ASAI Product Terms	Chat, roleplay, image and code generation
ASInstaller Terms	The desktop launcher and what it does on your computer
ASVentor Terms	All ASVentor media tools, including the downloader
ASMusic Distribution Terms	Distributing releases through ASMusic
Datasets Marketplace Terms	Buying and selling datasets on ETHERANE
Developer & API Terms	API keys, OAuth clients, rate limits

This is a convenience, not a trap. Three things follow from it, and they are binding on us:

You are only bound by what applies to you. A document governs a Service; if you never use that Service, its rules have nothing to operate on. The ASMusic Distribution Terms do not make you a distributor because you listened to a track.
A product document can never widen your obligations beyond these Terms. See the precedence rule below.
A material change to any of them is a change to this agreement, and gets the same 30 days' notice under Section 17 — we do not treat product terms as something we can rewrite quietly.

Precedence

Our rules are layered, and the order matters:

These Terms of Service. The top-level agreement.
Platform-wide policies. The Acceptable Use Policy, Privacy Policy, Refunds & Cancellation, Copyright & Takedown, DSA Notice & Action, Data Retention and the other documents in this section of the site.
Product-specific terms and policies. Rules that apply only to one product.

A lower layer can only narrow, never widen. A product-specific document may add detail, impose stricter rules, or restrict something further. It cannot grant you a permission that a platform-level document withholds, and it cannot lower a platform-level threshold. If a product document appears to allow something these Terms or a platform policy prohibit — including a lower minimum age — the platform-level document controls.

Where a lower-layer document is simply more specific about something the upper layers do not address, it applies as written.

4. Eligibility and age

You must be at least 16 years old to create an account or use the Services. This is a single platform-wide minimum and no product may set it lower.

Some content and features are restricted to users aged 18 and over, and we apply age gating where the law or the nature of the content requires it.

By using the Services you confirm that you meet the minimum age, that you have the legal capacity to enter into this agreement, and that you are not barred from using the Services under any law that applies to you.

If we reasonably believe an account belongs to someone under 16, we will restrict or close it. If you believe a child under 16 has an account with us, tell us at [email protected] and we will act.

Availability. We build for a global audience and we do not restrict access on the basis of nationality or country of residence. We do, however, have to comply with the law that applies to us, including EU and Estonian sanctions and export-control rules, and with valid orders from competent authorities. Where the law requires us to withhold or restrict a service, we will.

5. Your account and security

You are responsible for your account. That means:

Keep your password and any second factor (TOTP) secret, and use credentials you do not reuse elsewhere.
Do not share, sell, rent or transfer your account or let anyone else use it.
Give accurate registration details and keep your email address current — it is how we reach you about security, billing and changes to these Terms.
Tell us promptly at [email protected] if you think your account has been accessed by someone else.

Activity through your account is treated as yours unless you show otherwise. We may require you to verify your email address, re-authenticate, or complete additional security steps before performing sensitive actions.

Your internal account identifier (your handle) is used by our own systems to link your account across our Services. We do not disclose it to third-party applications or publish it as your public identity.

6. Your content and the licence you give us

You keep your rights. Everything you create, upload or publish through the Services — text, images, audio, code, datasets, messages — remains yours. We claim no ownership of it.

What you promise. By uploading content you confirm that you have the rights needed to do so, and that the content and its use through the Services do not infringe anyone else's rights or break the law or the Acceptable Use Policy.

The licence you give us. To run the Services we need permission to handle your content technically. You grant us a non-exclusive, worldwide, royalty-free licence to host, store, cache, back up, reproduce, transmit and display your content, and to make the technical modifications required to deliver it — for example transcoding audio, generating image thumbnails, or building preview images for links you share.

This licence is limited to operating, securing and improving the Services and to doing what you have asked us to do with the content — including publishing it to the audience you selected. It is not a licence to sell your content, to license it onward to third parties for their own purposes, or to use it in advertising.

It ends when you do. The licence ends when you delete the content or close your account, subject to two practical limits: copies may persist in backups until those backups rotate out (see Data Retention), and we may retain material where the law requires it or where it is needed to establish, exercise or defend a legal claim. Where you published content to others and they lawfully retained a copy, deleting your original does not undo that.

Training. We do not use your content to train AI models unless you turn that on. See AI Data & Training.

Our own material. The Services themselves — our software, interfaces, brand names, logos and documentation — belong to us or our licensors. Using the Services does not transfer any of those rights to you. Open-source components we ship remain under their own licences.

7. AI features

Where a Service generates output using AI models — ASAI, ETHERANE, and AI features inside other products — the following applies in addition to the product terms.

AI output is generated statistically. It can be wrong, outdated, biased or entirely fabricated, and it may resemble material produced for someone else. You are responsible for checking output before you rely on it, publish it, or use it in any context where accuracy matters. AI output is not professional advice of any kind. See AI Output & Limitations.

Your prompts and conversations are stored so the features work across sessions; how long, and what you can delete, is covered in Data Retention and the Privacy Policy.

We do not pre-screen AI output. We do act on reports about it, exactly as we act on reports about any other content (Section 10).

8. Acceptable use

The rules on what you may and may not do are in the Acceptable Use Policy, which forms part of this agreement. In short: nothing illegal, nothing that harms or endangers other people, no child sexual abuse material of any kind, no malware, phishing, spam or fraud, no attacks on our infrastructure or attempts to bypass our limits, no scraping or automated abuse, and no impersonation.

Breaking those rules is a breach of these Terms and can lead to the measures in Section 11.

9. Reporting illegal content or a rule breach

If you find something on the platform that is illegal or breaks our rules, report it to [email protected] with the subject line "Illegal content". Tell us where it is (a link or location), which Service it is on, and why you believe it is unlawful or in breach. We accept notices in English or Estonian.

We aim to confirm receipt within 72 hours and to assess notices in a timely, diligent and non-arbitrary way. The full procedure, including what a valid notice needs to contain, is in DSA Notice & Action. Copyright and trademark complaints have their own route — see the Copyright & Takedown Policy. Security vulnerabilities go to Responsible Disclosure.

10. How we moderate content

This section describes how content moderation actually works here, as required by Article 14 of the EU Digital Services Act.

We are reactive, not proactive. We do not generally monitor what you post, and we do not run automated content scanning across your posts, uploads or private messages looking for violations. We act when someone reports something, when a competent authority orders us to, or when we otherwise become aware of a problem — for example through our own operational monitoring.

What is automated. We use automated systems for infrastructure protection: rate limiting, spam and bot detection, abuse and fraud signals, and detection of anomalous account activity such as credential-stuffing patterns. These systems can automatically throttle a request, block traffic, or temporarily lock an account. They are aimed at behaviour and traffic, not at judging the meaning of your content.

Decisions are made by people. Where a decision affects your account or a specific piece of your content — removal, restriction, suspension, termination — a person makes or reviews that decision.

What we can do. Depending on the seriousness, intent and recurrence of the problem, we may remove or restrict content, limit its visibility, restrict features, suspend an account, or terminate it. We aim to be proportionate.

Statement of reasons. When we remove or restrict your content, or restrict or terminate your account, we will tell you what we did, why, whether it was based on the law or on our own rules, whether automated means were involved, and what you can do about it. This is the statement of reasons required by Article 17 of the Digital Services Act.

Disagree with a decision? Reply to the notice or write to [email protected] with the subject line "Appeal", explaining what you think we got wrong. A person will look at it again. We will tell you the outcome.

What we do not offer, and why. We are a micro enterprise. Article 19 of the Digital Services Act exempts providers of our size from the obligations in Section 3 of Chapter III — the formal internal complaint-handling system under Article 20, certified out-of-court dispute settlement bodies, and trusted-flagger priority handling — and Article 15(2) exempts us from publishing periodic transparency reports. We do not claim to operate those mechanisms. What we described above is what we genuinely do. Your right to go to court is unaffected (Section 19), and if we grow past the micro-enterprise threshold we will build what the law then requires and update this document.

Serious threats to life or safety. If we become aware of information giving rise to a suspicion that a criminal offence involving a threat to the life or safety of a person has taken place, is taking place or is likely to take place, we will inform the competent authorities, as Article 18 of the Digital Services Act requires.

11. Suspension, restriction and termination

You can leave at any time. Close your account from your account settings, or ask us at [email protected]. If you only want to stop paying, cancel the plan at https://subscriptions.aperturesyndicate.com — you do not have to close the account to stop a subscription. Closing your account cancels future renewals of any paid plan; it does not by itself refund the current period (Section 13 covers withdrawal, and Refunds & Cancellation covers the rest).

When we can act. We may restrict features, suspend, or terminate your account where:

you materially breach these Terms or the Acceptable Use Policy;
your use puts the platform, our users, or third parties at risk;
we are required to by law or by a valid order from a competent authority;
payment for a paid plan fails or is reversed and is not resolved; or
you have not used the account for a very long period and we have told you in advance that it will be closed.

Notice. Except where the breach is serious, unlawful, or ongoing and harmful, we will give you notice and, where it is reasonable to do so, an opportunity to fix the problem before we act. In every case you get a statement of reasons under Section 10.

Immediate termination without warning is reserved for the most serious cases: child sexual abuse material, credible threats of violence, large-scale attacks on our systems, and comparable conduct.

What happens to your data. After closure or termination, your data is soft-deleted immediately and permanently purged after a grace window of about 30 days, except where a longer retention is legally required — invoices in particular are kept for 7 years. During the grace window you can ask us for a copy of your data (Section 5 of the Privacy Policy). See Data Retention for the full schedule.

We can also discontinue a Service. If we retire a product, we will give reasonable advance notice, and if you have paid for a period you will not receive, we will refund the unused part pro rata.

12. Paid plans, prices and auto-renewal

Some Services are free; some have paid plans and optional add-ons. The in-app pricing page is the authoritative source for what each plan costs and includes.

Currency and VAT. Prices are in EUR. Applicable VAT is calculated and shown at checkout based on your location and is included in the amount charged. Where a price is displayed without tax, that is stated and the final checkout total includes it.
Payment. Payments are processed by Stripe. We do not store your full card details.
Auto-renewal. Paid plans renew automatically at the end of each billing cycle at the then-current price for that plan, until you cancel. Your billing cycle and next renewal date are shown in your account billing settings.
Cancelling. You can cancel at any time, without giving a reason, from your account settings in the product itself or from https://subscriptions.aperturesyndicate.com, which shows every paid plan you hold with us in one place and cancels any of them. Cancelling stops future renewals; your paid access continues until the end of the period you already paid for. You do not need to contact us to cancel.
Price changes. A price change never applies retroactively to a period you have already paid for. We will give you at least 30 days' notice before a change takes effect at your next renewal, so you can cancel first if you do not want to continue.
Failed payments. If a payment fails, we may retry it and may suspend paid features until it succeeds.
Billing questions. Write to [email protected]. We aim to acknowledge billing queries within 5 business days. Please talk to us before opening a chargeback — it is almost always faster.

Full details, including the situations where we refund outside the withdrawal period, are in Refunds & Cancellation.

13. Your 14-day right of withdrawal

If you are a consumer in the EU, you have the right to withdraw from a paid contract with us within 14 days, without giving any reason.

We do not ask you to waive this right. EU law lets a provider of digital services ask the consumer to give up the withdrawal right in exchange for immediate access. We do not do that. Your 14 days are real.

The period runs for 14 days from the day the contract is concluded — that is, from the day you start the paid plan or buy the add-on.

How to withdraw. Send us a clear statement that you are withdrawing, to [email protected] from the email address on your account. You can use the model form below, but you do not have to. Sending the statement before the 14 days are up is enough — we do not need to have replied.

What we refund. We refund all payments received for the withdrawn contract, without undue delay and no later than 14 days after we are informed, using the same payment method you used, with no fee for the refund itself.

One fair deduction. If you asked us to start the service immediately and you used it before withdrawing, we may deduct an amount proportionate to what you actually used, measured against the full contract. Nothing more. If you did not use the service, you get everything back.

What withdrawal does not cover. The right applies to contracts you enter into as a consumer at a distance. It does not apply to a renewal you allowed to happen after your original 14 days had passed — for that, cancel before the renewal date under Section 12 — and it does not apply where you are contracting in the course of a business.

Model withdrawal form

You may use this form, but you are not obliged to.

Address:        ..............................................

Signature (only if this form is sent on paper): ..............
Date: ........................................................

14. Availability and changes to the Services

We work to keep the Services running and secure, but we provide them on an "as available" basis. There may be downtime for maintenance, faults, or reasons outside our control. We do not offer a contractual uptime guarantee unless a specific product term says otherwise.

We may add, change, or remove features. Where a change materially reduces what a paid plan gives you, we will give you at least 30 days' notice and you may cancel and receive a pro-rata refund for the unused part of the period.

Beta and preview features are exactly that: they may be unstable, may change, and may disappear.

15. Warranties and liability

What we promise. We will provide the Services with reasonable care and skill and in accordance with these Terms. If you are a consumer, you also have statutory rights regarding the conformity of digital content and services under EU and Estonian law, and nothing here affects them.

What we do not promise. Beyond the above, and to the extent permitted by law, the Services are provided without further warranties — we do not warrant that they will be uninterrupted, error-free, or that AI output or third-party data will be accurate or fit for any particular purpose.

Limitation of liability. To the extent permitted by mandatory law, we are not liable for indirect or consequential loss, loss of profit, loss of business, or loss of data that you could have avoided by keeping your own copies. Our total liability arising out of or in connection with the Services in any twelve month period is limited to the greater of (a) the amount you paid us for the Services in the twelve months before the event giving rise to the liability, and (b) €100.

What is never excluded. Nothing in these Terms excludes or limits our liability for death or personal injury caused by our negligence, for fraud or fraudulent misrepresentation, for intent or gross negligence, for any liability under mandatory product-liability law, or for anything else that cannot be excluded or limited under the mandatory law of Estonia or of your country of residence as a consumer. Where a limitation in this Section conflicts with such mandatory law, the law prevails and the rest of the Section still stands.

If you use the Services for business purposes, you are responsible for claims brought against us by third parties that arise from your content or your use of the Services in breach of these Terms, to the extent the claim results from your breach. This does not apply to consumers.

16. Third parties

Some Services connect to third-party platforms and providers — payment processing, AI inference, music distribution, media sources and others. Their services are governed by their own terms, and we are not responsible for how they operate. Who processes what on our behalf is listed in Data Processing & Sub-processors.

Lysicon Quanture publishes market and analytics content. It is information, not investment advice — see the Financial Disclaimer.

17. Changes to these Terms

We may update these Terms — for example when we add a product, when the law changes, or when we correct something.

For any material change, we will give you at least 30 days' notice before it takes effect, by email to the address on your account or by a clear notice in the product, and we will update the "Effective date" at the top of this page.

If you do not accept a change, you may close your account before it takes effect, without penalty; if you have paid for a period you will not use, we will refund it pro rata. Continuing to use the Services after the effective date means you accept the new version.

Minor corrections that do not affect your rights or obligations — typos, clarifications, updated links — may be made without notice.

18. Notices

We send notices to the email address registered on your account, or show them in the product. Keep your address current. You send notices to us at [email protected], in English or Estonian.

19. Governing law, jurisdiction and disputes

These Terms and any dispute arising from them are governed by the law of Estonia, and the courts of Tallinn have jurisdiction.

If you are a consumer, this does not deprive you of the protection of the mandatory provisions of the law of the country where you live, and you may bring proceedings in the courts of that country. We will bring any claim against a consumer only in the courts of the country where the consumer lives.

Before going to court, talk to us. Write to [email protected] — most disputes turn out to be something we can simply fix.

Consumer dispute resolution. If we cannot resolve a complaint between us, a consumer in Estonia may refer the matter to the Tarbijavaidluste komisjon (Consumer Disputes Committee) at the Tarbijakaitse ja Tehnilise Järelevalve Amet (TTJA) — https://www.ttja.ee · [email protected]. Consumers elsewhere in the EU may use the equivalent body in their own country. We are not obliged to use, and have not committed to using, any particular certified out-of-court dispute settlement body, but we will engage constructively with a consumer authority that contacts us.

Data-protection complaints go to Andmekaitse Inspektsioon (Estonian Data Protection Inspectorate) — see the Privacy Policy.

20. Language

These Terms are published in English and in translation. The English version is the controlling version. If a translation and the English version differ, the English version applies. This does not affect any right you have under mandatory law to receive information in your own language.

21. General

Severability. If any provision is held invalid or unenforceable, the rest remains in force, and the invalid provision is replaced by the closest valid one.
No waiver. If we do not enforce a right immediately, we do not lose it.
Assignment. You may not transfer your rights under these Terms without our consent. We may transfer ours to a successor of our business, provided your rights are not reduced.
Force majeure. Neither party is liable for a failure caused by events beyond its reasonable control.
Entire agreement. These Terms, together with the documents referenced in Section 3, are the whole agreement between us about the Services.
No third-party rights. These Terms create rights only between you and us.

v2.2 — 2026-08-01 — Chat replaced by Support. The user-to-user messenger has been withdrawn; the Services list and the document hierarchy now describe support requests instead, and the separate Chat Terms are gone. Nothing about your rights changes: a feature nobody used was removed, and the documents were corrected to match.
v2.1 — 2026-08-01 — ASInstaller, the Creator portal and the subscriptions portal added to the services list; Section 3 now states plainly that accepting these Terms accepts every product document with them, lists those documents, and commits us to the same notice period for changes to any of them; cancellation now points at https://subscriptions.aperturesyndicate.com.
v2.0 — 2026-07-31 — Full rewrite: services list corrected, document hierarchy and precedence added, minimum age set at 16, honest 14-day right of withdrawal with model form, content moderation described as actually practised under DSA Articles 14, 16, 17 and 18 with the Article 19 micro-enterprise position stated openly, liability limited subject to mandatory law, governing law, jurisdiction, consumer dispute resolution, change-notice period and language precedence added.
v1.0 — 2026-06-22 — Initial publication.
