Terms of Service

The agreement between you and Mivia for use of the service.

Acceptance of these Terms

By creating a Mivia Sign account or using any part of the service, you agree to these Terms of Service ("Terms"). If you don't agree, don't use the service. These Terms form a binding agreement between you and Venezia LLC, a Wyoming limited liability company trading as Mivia ("Mivia", "we", "us").

The service

Mivia Sign embeds inaudible cryptographic signatures into audio files and lets those signatures be verified. The service includes the website at this domain, the Mivia Sign DAW plugin (AU / VST3 / CLAP), and related APIs.

We may add, change, or remove features. We will give reasonable notice of material changes that reduce functionality you are currently paying for.

Your account

Eligibility. You must be at least 16 years old to create a Mivia Sign account. You must be at least 18 years old to subscribe to a Pro plan, because our payment processor (Stripe) requires the account holder of a paid subscription to be 18 or older. If your jurisdiction sets a higher age of digital consent than 16, that higher age applies. We don't direct the service to anyone below these ages. If we find out someone is below the applicable age, we will close the account.

Accuracy. Give us accurate information when you register and keep it up to date.

Security. Keep your credentials confidential and tell us promptly at [email protected] if you think your account has been accessed without your authorisation. You are responsible for activity on your account. "Credentials" means whichever sign-in factors you have enabled: your password, any passkeys you have registered, your authenticator-app code if you have two-factor authentication enabled, and the single-use backup codes generated when you turn two-factor on. Passkeys are tied to the device or keychain that holds them. If you can no longer sign in with a passkey, sign in another way and remove the unreachable key from account settings before adding a new one. Treat backup codes the way you would a password. Each works once.

Electronic communications. By using Mivia Sign, you agree that we may send you notices, including legal notices and notices about changes to the service, by email to the address on your account and by in-app message. Email satisfies any requirement that a notice be in writing.

Acceptable use

You agree not to:

  • Sign audio you do not have the rights to sign, or falsely claim authorship of work you did not create.
  • Upload content that infringes third-party rights, violates applicable law, or is intended to harass, defame, or deceive.
  • Reverse-engineer, disassemble, or attempt to bypass our watermarking, verification, or OpenTimestamps systems.
  • Use the service to distribute malware, conduct automated abuse, or interfere with the operation of the service.
  • Resell, sublicense, or wrap the service in a product you charge others for without our prior written permission. If you want to build commercial detection or verification on top of Mivia, write to [email protected].

We may suspend or terminate accounts that breach this section. We reserve the right to cooperate with law enforcement and to disclose account information where required by law.

Your content and authorship

You keep all rights to the audio you upload and the metadata you submit ("Your Content"). You grant Mivia a limited, worldwide, royalty-free licence to process Your Content solely to provide the service: to watermark, store, and make it available for verification at your direction.

When you sign a track, Mivia records a manifest (a track identifier, the watermark, a timestamp, and the public half of your signing identity) and anchors it to Bitcoin via OpenTimestamps. These records are intentionally permanent and are how authorship is later proved. You can delete your account (see Termination), but the on-chain anchor itself is immutable by design (see Permanent on-chain records).

Mivia's intellectual property

The Mivia Sign service, plugin, website, brand assets, and underlying watermarking technology are the property of Mivia. We grant you a personal, non-transferable, revocable licence to use the service under these Terms. Nothing here transfers ownership of any Mivia intellectual property to you.

"Mivia", "Mivia Sign", and associated logos are trademarks of Venezia LLC. Don't use them without our written permission, except to refer to the service in ordinary descriptive language.

DAW plugin licence

The Mivia Sign DAW plugin (AU, VST3, CLAP) is part of the service covered by these Terms and is included with an active Pro subscription. While your Pro subscription is active we grant you a personal, non-exclusive, non-transferable, revocable licence to install and use the plugin on machines you own or control, solely to sign audio you are entitled to sign.

You will not redistribute the plugin, sub-license it, reverse-engineer it, or use it outside an authenticated Mivia Sign session. When your subscription ends or your account is closed, your licence to the plugin ends and you must uninstall it. The plugin is covered by the same warranty disclaimer and limitation of liability as the rest of the service.

Recipient labels (data-processing agreement)

When you attach a recipient label to a signed track (for example, the name or email of an A&R contact you have sent a copy to), you are the data controller of that recipient's personal data and Mivia acts as a data processor on your behalf. This section, together with our Privacy Policy, forms the data-processing agreement (DPA) required by Article 28 of the GDPR and UK GDPR for that processing.

Scope. We process recipient labels only to store them against your signed manifest, display them to you, and surface them in the scan activity for that manifest.

Your instructions. We process labels on your documented instructions, which are the actions you take in the product (creating, editing, or deleting a label). We won't use labels for any other purpose, won't disclose them to third parties except as required by law, and will tell you if a legal obligation requires us to act outside your instructions, unless we are prohibited from telling you.

Your responsibility. You confirm you have a lawful basis under applicable data-protection law for naming each recipient. Where appropriate, you should tell the recipient that the track they have received is watermarked.

Confidentiality. Mivia personnel with access to labels are bound by confidentiality obligations.

Sub-processors. We use the sub-processors listed in our Privacy Policy (Cloudflare, Stripe, Resend) to run the service. You authorise these sub-processors. We will tell you before we add or replace one, and you can object by closing your account.

Security and transfers. We apply the security measures and international-transfer mechanisms set out in our Privacy Policy.

Data-subject rights. If a recipient contacts Mivia to exercise rights over a label, we will forward the request to you because you are the controller. You must respond within the timeframes your local law requires.

Information rights. On reasonable written request, and no more than once a year, we will give you the information you need to demonstrate compliance with Article 28 obligations. On-site audits are not available at the Pro tier.

Deletion. When you close your account, we delete the related label data in line with the retention section of the Privacy Policy, including its backup carve-out. To delete an individual label or manifest before closing your account, email [email protected].

Liability. Our liability under this section is subject to the overall limitation of liability in these Terms.

Permanent on-chain records

Each track you sign produces a cryptographic timestamp anchored to the Bitcoin blockchain through OpenTimestamps. By the nature of public blockchains, the anchor is permanent, public, and outside Mivia's control. By signing a track, you acknowledge:

  • The on-chain anchor cannot be deleted, modified, or recalled by Mivia, by you, or by anyone else, once created.
  • The anchor itself contains a hash, not your name, your email, or the audio. It is not personally identifying on its own.
  • When you delete a manifest or close your account, we remove the records on our side that link the anchor back to you. The anchor itself remains on the blockchain.
  • You should not sign tracks you do not intend to commit to a permanent record.

If you do not want to create a permanent record, do not sign the track.

Public certificate pages

Every Mivia signature has a public certificate page at /c/<mivia-id>. The page is open to anyone, no Mivia account required. When you sign a track you are publishing this certificate, and you should treat it as public from the moment of signing.

The certificate shows the title and creator name you provided at sign time, the date of signing, the Mivia ID, and the Bitcoin transaction that anchors the record. It does not show your library, your scan history, your collaborators, or the recipients of any per-recipient variants. Those stay private to your account.

Anyone with a Mivia ID can paste it at /database to open the matching certificate. Anyone with the audio file can scan it at /scan to reach the same record. Neither route requires a Mivia account.

Renaming a track in your library after signing changes the display title in your own account only. The title shown on the public certificate is the one you provided at sign time and cannot be edited afterwards.

What the service is and isn't

Mivia Sign is a tool, not a guarantee. A few things you should understand about how it works:

Watermark survival. Our watermarks are designed to survive normal distribution: lossy compression (MP3, AAC, Opus), format conversion, mastering, EQ, dynamics, and screen-capture playback. They are not guaranteed to survive aggressive transformations such as heavy time-stretching, large pitch shifts, re-tracking in a DAW, re-recording through a microphone in a noisy environment, deliberate adversarial removal, or remastering by a human engineer trying to defeat the mark.

Not legal evidence on its own. A Mivia signature is a technical record: a hash of your audio, a public signing key under your control, and a Bitcoin-anchored timestamp. It is evidence that a specific file existed at a specific time and was signed by the holder of a specific key. It is not a legal determination of authorship, ownership, or infringement. We do not provide expert-witness services, courtroom testimony, or chain-of-custody attestations. You may submit our technical records as exhibits in your own proceedings; what they prove is for that forum to decide.

Per-recipient labels are evidence, not proof. When you sign one track for several recipients and a copy later turns up on a public site, the recipient label on the matching copy tells you which labelled copy was scanned. It does not, on its own, prove that the named recipient leaked the file. They may have shared it under your authorisation, had a machine compromised, lost a drive, or passed it on. Treat the label as a strong signal that warrants a conversation, not as a conclusion.

Subscriptions and billing

The Free plan gives limited access at no charge. The Pro plan is offered at the prices shown on the Pricing page, in US dollars. Currently: $12.99 per month or $129 per year. Prices are stated exclusive of taxes; VAT, GST, or sales tax is added at checkout where Stripe Tax determines it applies, and is remitted by Stripe.

Payment processor. Payments are handled by Stripe. Stripe collects your card details directly; we never see your card number. By subscribing, you also accept Stripe's terms.

Auto-renewal and your consent. Your subscription renews automatically at the end of each billing period (monthly or annual) at the then-current price, until you cancel. By clicking Subscribe at checkout, you give your express affirmative consent to the recurring charge, the billing frequency, the price, and the cancellation procedure. Stripe retains the consent record.

Cancellation. You can cancel at any time using the Manage button on the Pricing page (which opens Stripe's customer portal) or by emailing [email protected]. Cancellation takes effect at the end of the current billing period; Pro features remain available until then. We don't require a phone call, a mailed letter, or a retention conversation.

Refunds. Payments are non-refundable except where required by law (including the EU and UK cooling-off rights below) or where we choose to issue a refund at our discretion. Cancellation stops future renewals; it doesn't refund the current period.

Renewal notices. Where applicable consumer-protection law (including the California and other state automatic-renewal statutes referenced below) requires advance notice of a renewal, you'll receive a reminder email before the charge, showing the renewal date, the amount, and a link to cancel.

Failed payments. If a charge fails, Stripe retries on its standard schedule (typically up to four attempts over about two weeks). If all retries fail, your Pro features pause and your account reverts to Free. We do not delete your data during the grace period.

Price changes. We may change prices for future billing periods. We will give you at least 30 days' notice by email before any price increase takes effect on your subscription, and you can cancel before it does.

California, New York, Florida and other states with automatic-renewal laws. The above terms are intended to satisfy California Business and Professions Code §§17600 et seq. (including AB 2863), New York General Business Law §527-a, Florida Statutes §501.165, and similar laws. You can cancel through the same channel you used to subscribe and we'll retain your renewal-consent record for the period these laws require.

EU and UK cooling-off period

If you live in the EU, EEA, or UK and you are buying for personal use, you have 14 days from your subscription date to cancel and receive a refund, without giving a reason. To use the right, email [email protected] or cancel from your account before the 14 days are up.

Mivia Sign is a digital service. By starting to use the service during the 14-day period (for example, by signing a track), you expressly consent to immediate performance and acknowledge that you lose the right to withdraw once performance has begun. If you withdraw after starting to use the service but before the period ends, we may charge a proportionate amount for the use you made of it.

Termination

By you. You can close your account at any time from Your settings.

By us, for cause. We may suspend access immediately, without notice, if we reasonably believe you are materially breaching these Terms, that your account is compromised, or that immediate action is required to protect the service or its users. Where possible we'll tell you what's wrong and give you a chance to fix it. We may terminate for material breach or non-payment on 30 days' notice, or immediately for fraud, illegal use, abuse of staff, repeated infringement, or where the law requires.

By us, for convenience. We may retire the service or any plan on 90 days' notice by email. If we do this while you have a paid subscription, we will refund any prepaid fees for the unused portion of the term.

Data export window. For 30 days after termination of a paid account, you can request export of your signed-track manifests and account data by emailing [email protected]. After 30 days we delete in line with the retention schedule in the Privacy Policy.

After termination. Bitcoin-anchored manifests remain publicly verifiable, as described under Permanent on-chain records. That is the point of the service.

Warranty disclaimer

The service is provided "as is" and "as available". To the maximum extent permitted by law, Mivia disclaims all warranties, express or implied, including merchantability, fitness for a particular purpose, non-infringement, and uninterrupted or error-free operation. You use the service at your own risk.

Nothing in this section limits or excludes any statutory right you have as a consumer that cannot be limited or excluded by law. If you are a UK consumer, this includes your rights under the Consumer Rights Act 2015. If you are an EU or EEA consumer, this includes your statutory rights under EU consumer protection law.

Limitation of liability

To the maximum extent permitted by law, Mivia's total aggregate liability to you for any claim arising out of or relating to the service, whether in contract, tort (including negligence), strict liability, or otherwise, will not exceed the greater of US$100 or the fees you paid Mivia in the twelve months before the event giving rise to the claim. Mivia is not liable for indirect, incidental, special, consequential, or punitive damages, or for loss of profits, revenue, data, or goodwill.

Nothing in these Terms excludes or limits liability for: (a) fraud or fraudulent misrepresentation; (b) gross negligence or wilful misconduct; (c) death or personal injury caused by our negligence; (d) for UK consumers, your rights under the Consumer Rights Act 2015; (e) for EU and EEA consumers, your statutory rights under EU consumer protection law; or (f) any other liability that cannot be excluded under applicable law.

Indemnity

You agree to defend, indemnify, and hold harmless Mivia, its officers and contractors from any third-party claim, demand, loss, or expense (including reasonable legal fees) arising out of: (a) Your Content, including audio you sign and recipient labels you attach; (b) your breach of these Terms or applicable law; or (c) your infringement of any third party's intellectual property, privacy, or publicity rights.

We will tell you promptly about any covered claim, give you reasonable cooperation, and not settle without your consent (not to be unreasonably withheld). You may control the defence with counsel of your choice, subject to our right to participate.

For consumers in the EU, UK, and other jurisdictions where consumer indemnity obligations are limited by law, this indemnity applies only to the extent permitted by that law and only to claims arising from your wilful misconduct or breach of these Terms.

Copyright notices

We respect copyright. If you believe content on Mivia Sign infringes your copyright, send a notice to [email protected].

A compliant notice should include: your physical or electronic signature; identification of the copyrighted work; identification of the material you claim is infringing and where it is on the service; your contact information; a statement that you have a good-faith belief that the use is not authorised by the copyright owner, its agent, or the law; and a statement, under penalty of perjury, that the information is accurate and that you are authorised to act on the copyright owner's behalf. We respond to properly formed notices, may send counter-notices, and may terminate the accounts of repeat infringers.

Changes to these Terms

We may update these Terms. Material changes are announced at least 30 days in advance by email and an in-app notice. If you continue to use the service after the effective date, you accept the updated Terms. If you don't agree, you can close your account before the change takes effect and, where you've prepaid for a future period, we'll refund the unused portion.

Governing law and disputes

These Terms are governed by the laws of the State of Wyoming, without regard to conflict-of-laws rules. The state and federal courts located in Wyoming have exclusive jurisdiction over any dispute.

Consumer carve-out. If you are a consumer resident in the EU, EEA, UK, or Switzerland, nothing in this section deprives you of the protection of the mandatory consumer-protection rules of your country of habitual residence, or of the right to bring proceedings in the courts of that country where local law guarantees that right.

General

Entire agreement. These Terms, together with our Privacy Policy, are the entire agreement between you and Mivia about the service and replace any earlier agreement on the same subject.

Severability. If any part of these Terms is held unenforceable, the rest stays in force.

No waiver. If we don't enforce a term, that isn't a waiver of our right to enforce it later.

Assignment. We may assign these Terms in connection with a merger, acquisition, or sale of all or substantially all of our assets, on at least 30 days' advance notice by email. You may not assign these Terms without our written consent.

Force majeure. We aren't responsible for delay or failure to perform caused by events outside our reasonable control, including natural disasters, war or civil unrest, government action, large-scale internet or infrastructure outages, and major denial-of-service attacks. We'll use reasonable efforts to resume normal performance as soon as the event passes.

Headings. The section titles in these Terms are for reference only and do not affect interpretation.
