2. What the extension does

Acridan Audio is a browser extension that applies real-time audio effects to supported media websites. YouTube and YouTube Music are available on the free tier. SoundCloud requires an active Pro trial or paid Pro subscription.

Acridan Audio is independent. YouTube, YouTube Music, and SoundCloud are third-party platforms and do not endorse or sponsor Acridan Audio. We use Supabase for authentication and subscription infrastructure, Polar for checkout and subscription administration, and Featurebase only if you open the feedback board.

3. License and acceptable use

Subject to these Terms, we grant you a limited, non-exclusive, non-transferable license to install and use the extension for your personal, non-commercial use, or for your internal business use, in each case only in accordance with these Terms.

• do not use the extension in violation of law or third-party rights
• do not interfere with, disrupt, or abuse the extension, premium backend, or related infrastructure
• do not bypass or attempt to defeat premium restrictions or premium-access checks
• do not share, resell, sublicense, transfer, or commercially exploit your account or premium access except where we expressly allow it
• do not reverse engineer or attempt to extract source code or security mechanisms except to the extent such restriction is prohibited by applicable law

4. Premium subscription, browser installations, and access checks

Some features require a signed-in account and either an active Pro trial or paid premium subscription. Premium access may depend on authentication, browser-installation registration, ongoing validation, fraud controls, and service availability.

The current five-day free trial starts when the Supabase account is created. No payment information is required. After the trial expires, premium features revert to the free tier unless you subscribe. Creating another browser profile or reinstalling the extension does not start a new trial for the same account. Trial availability, duration, and scope may change for future users.

Premium access is licensed for one account holder only. One account may have no more than five registered browser installations at a time. Each browser profile or extension installation counts separately, including two browsers on one computer. Signing out does not free a slot. Clearing extension data or reinstalling may require a new registration. Installations can be viewed, renamed, and removed in the extension.

For signed-in users, the extension may synchronize custom presets, shortcuts, global visual settings, fullscreen behavior, and general song-memory preferences. It does not synchronize per-site or per-track mappings, URLs, media identifiers, listening history, artwork, audio, or other media content. The most recently accepted change may replace an earlier synchronized configuration.

Preset copy, import, or export controls concern configuration data only. The extension does not record, download, or export audio or other media content.

• currently supported sites: YouTube and YouTube Music on the free tier; SoundCloud with an active Pro trial or paid Pro subscription
• account authentication, browser-installation registration, synchronization, premium validation, and restoration require an internet connection and availability of Supabase and Polar
• local premium restoration can require another sign-in after browser cleanup, profile changes, reinstalling the extension, or switching browsers or computers
• compatibility depends on supported browsers, browser versions, and the current technical behavior of the supported sites

5. Billing, renewals, cancellations, and withdrawals

No payment is collected during the free trial. The free trial does not create a subscription or billing obligation. The statutory withdrawal period for a paid subscription begins when the paid subscription contract is concluded, not when the free trial starts.

Premium access is offered as a recurring subscription. The applicable price, taxes, billing interval, renewal terms, and cancellation method are shown at checkout.

Current paid checkouts are administered by Polar as merchant of record or reseller. Polar is identified as the seller on checkout, invoices, tax documents, or payment statements and its buyer terms apply to the transaction. Acridan remains the provider of the extension and product support. If the seller changes, checkout will identify the new seller before payment.

Recurring charges apply only as disclosed at checkout and continue until you cancel through the customer portal, provider flow, or other process identified in that purchase flow. Unless stated otherwise at checkout, cancellation of a recurring plan takes effect at the end of the current billing period.

We do not apply a new price to an existing consumer subscription merely under a general change clause. Existing customers are kept on their agreed price unless a lawful, specifically disclosed adjustment mechanism applies or they expressly accept a new plan.

If you are a consumer and applicable law gives you a right to withdraw from a distance purchase, that right remains unaffected. The standard withdrawal period is 14 days unless applicable law provides otherwise. The withdrawal period starts on the day the contract is concluded. To exercise a statutory withdrawal right, send an unequivocal statement before the withdrawal period expires to [email protected], use the withdrawal form on this website, or use the customer-support or provider path identified in the purchase flow where available.

If the seller named in checkout, on the invoice, or on the payment record is Polar or another merchant of record or reseller, the withdrawal may also be directed to that seller. If you send it to us, we will confirm receipt and coordinate it where needed.

If you withdraw, the seller must reimburse all payments received for the withdrawn contract without undue delay and no later than 14 days after the day the withdrawal is received, using the same means of payment you used for the original transaction, unless you expressly agree to a different means and incur no fees as a result.

If you expressly ask the seller to begin supplying premium access during the withdrawal period and later withdraw, you may owe a proportionate amount for service already supplied where permitted by law and after the required information was provided. Merely starting an ongoing digital service does not itself extinguish the withdrawal right. Loss of the right applies only after full performance and when every statutory consent and acknowledgment condition is met.

Cancellation stops future renewal and normally leaves access active through the paid period. Statutory withdrawal rescinds the contract and requires both any applicable reimbursement and termination of future billing. Defective-service remedies and optional goodwill refunds are separate and remain unaffected.

Nothing in these Terms limits any mandatory right to a refund, price reduction, reimbursement, termination, conformity remedy, or other consumer remedy available under applicable law.

6. Third-party providers, supported sites, and changes

Parts of the extension or premium service rely on third-party providers including Supabase, Polar, and Featurebase. Your use of YouTube, YouTube Music, SoundCloud, and any other third-party platform remains subject to that platform's own terms, policies, and technical limitations.

We may modify, suspend, limit, or discontinue parts of the extension or premium service for valid reasons, including security, fraud prevention, legal or compliance requirements, technical changes to browsers or supported sites, infrastructure changes, or product improvements.

For paid access supplied over time, material changes that negatively affect premium functionality apply prospectively only and at no extra cost. If a change negatively affects your access or use more than only a minor amount, we will give advance notice on a durable medium and a free right to terminate within 30 days of the notice or the change taking effect, unless applicable law allows a different solution that fully preserves your rights.

If paid premium functionality becomes materially unavailable during a prepaid period and we do not restore substantially similar functionality within a reasonable time, any mandatory rights to reimbursement, price reduction, termination, or other consumer remedies remain unaffected.

7. Consumer rights, intellectual property, and liability

Nothing in these Terms excludes or limits any mandatory rights available to consumers under applicable law. This includes mandatory rights relating to withdrawal, conformity of digital content or digital services, required updates, price reduction, reimbursement, or termination.

The extension, premium services, branding, software, visual design, and related materials are owned by us or our licensors and are protected by applicable intellectual property laws. These Terms do not give you any right to our trademarks, source code, backend systems, or other proprietary materials except for the limited use license above.

To the maximum extent permitted by law, the extension and premium services are provided "as is" and "as available." We do not guarantee uninterrupted availability, ongoing compatibility with supported sites, or that settings, presets, or premium state will never be lost or corrupted.

For business users only, and to the maximum extent permitted by law, our total aggregate liability arising out of or relating to the extension and premium services will not exceed the greater of the amount paid for premium access in the 12 months before the event giving rise to the claim or EUR 50. This does not limit liability that cannot be limited under applicable law. Mandatory consumer warranty, conformity, update, remedy, and liability rights are not limited.

8. Changes to these Terms

We may update these Terms from time to time. Material changes apply prospectively only.

If we make a material change affecting paid premium access, we will give notice before the change takes effect. If you do not agree to the change, you may cancel before the next renewal.

No update will retroactively reduce rights that already accrued. Where applicable law requires a different notice, consent, or termination process, we will follow that law.

9. Suspension, termination, governing law, and miscellaneous

We may suspend or terminate premium access if you materially violate these Terms, we reasonably suspect fraud, abuse, chargeback misuse, or unauthorized sharing of premium access, we are required to do so by law, payment provider action, security concerns, or a third-party premium-validation provider decision, or continued service would create a material legal, security, or operational risk. Where reasonably practicable, we will give notice and an opportunity to cure before suspension or termination, except in urgent fraud, abuse, chargeback, or security situations. A good-faith payment dispute or the exercise of a statutory right is not itself abuse.

If we terminate paid premium access without cause attributable to you before the end of a prepaid period, we will provide any refund or other remedy required by applicable law.

These Terms are governed by Austrian law unless mandatory consumer protection law in your country of residence requires otherwise. Business-user jurisdiction is Vienna where legally permitted; mandatory consumer venue rights remain unaffected. We do not currently participate in consumer ADR. If a complaint cannot be resolved, we provide the information required by section 19 AStG on a durable medium.

If any provision of these Terms is unenforceable, the remaining provisions remain in effect to the extent permitted by law. Our failure to enforce a provision is not a waiver of that provision.
