Terms & Conditions
Last updated: September 23, 2026
Short version: buy once (€5.99 via Polar.sh), use Trisle forever on your own Android devices, keep your receipt for retrieval, and get a full refund within 7 days if it is not for you. The complete terms are below.
1. Agreement and scope
These Terms and Conditions (“Terms”) form a binding agreement between you and the operator of Trisle (“Operator”, “we”, “us”) governing your use of:
- the Trisle Website at trisle-app.github.io/Trisle_Website (“Website”), including its content, marketing materials and purchase flow; and
- the Trisle application for Android (“App”), which you license from us as described in section 5.
By using the Website, purchasing the App, or installing or using the App, you accept these Terms. If you do not accept them, do not use the Website or the App. The Privacy Policy (trisle-app.github.io/Trisle_Website/privacy) is incorporated into these Terms by reference and describes how we handle data.
2. Definitions
- “Device” — an Android phone or tablet that you own or control.
- “Polar” — Polar.sh, the merchant of record that processes checkout, payment, taxes and refunds for the App.
- “Checkout reference” — the unique identifier Polar attaches to your order (visible in your receipt and in the confirmation URL), used to retrieve your purchase and to process refunds.
3. Who may use the App
You must be at least the age at which you can enter into binding contracts in your country (in the EU generally 18, in some cases 16 with parental consent) or have the consent of a parent or legal guardian. You may use the App only on Devices that you own or control, and only in compliance with all laws applicable to you.
4. Use of the Website
The Website is provided for information about the App and for purchasing it. You agree not to:
- interfere with, overload, or attempt to gain unauthorised access to the Website or related systems;
- scrape, copy, or republish substantial parts of the Website’s content without our prior written permission (short quotations with a link are fine);
- use the Website to distribute unlawful, infringing, or harmful content, or for any fraudulent purpose;
- circumvent or attempt to circumvent any security or access control.
5. License grant
The App is licensed, not sold. Subject to your continued compliance with these Terms and your completion of payment, we grant you a personal, worldwide, non-exclusive, non-transferable, non-sublicensable and perpetual license to install and use the App on Devices that you own or control, for your private use. Because the App is a one-time purchase, the license does not expire and there is no subscription: one payment, yours forever.
Proof of purchase travels with your Polar receipt and the checkout reference in your confirmation link. Keep the receipt email — it is the key to re-retrieving your purchase and to refunds.
6. License restrictions
You may not, and may not allow others to:
- redistribute, resell, rent, lease, lend or sublicense the App or access to it, whether for money or free of charge;
- publish the App or its installable files on other stores, file-sharing services, or repositories;
- modify, reverse engineer or decompile the App except to the extent that applicable law expressly permits it despite this limitation;
- remove, obscure or alter any proprietary notice in the App;
- use the App to build a competing product, or in any unlawful way.
Where the law of your country gives you mandatory rights that these restrictions would otherwise limit (for example rights of decompilation for interoperability), those rights prevail.
7. Purchase, price and payment
The App is offered for a one-time price of €5.99. Checkout is operated by Polar as merchant of record: Polar collects the payment, handles applicable VAT/GST and other indirect taxes, issues the receipt, and processes refunds. We never receive or store your full payment instrument details. The displayed price includes applicable taxes where required by law; your final price is shown on the checkout page before you pay. We may change the price at any time, but the change never affects an order that has already been completed.
8. Delivery and retrieving your purchase
The App is digital content delivered immediately after payment: your confirmation page (the “success” page, reachable through the checkout flow and identifiable by your checkout reference) and your Polar receipt email contain everything needed to download and activate the App. If you lose access, the receipt email and your checkout reference are sufficient to retrieve your purchase at any time — no account is required.
9. Statutory withdrawal right and our refund policy
EU/UK consumers: for digital content not supplied on a tangible medium, you have a statutory 14-day right of withdrawal. When you purchase, you expressly consent to immediate performance of the contract and acknowledge that, once delivery of the digital content begins, you lose your statutory right of withdrawal. To make this transparent, the checkout presents this acknowledgment before payment.
Our voluntary promise on top: independent of the above and more generous than many statutory regimes, we refund any purchase in full if you tell us within 7 days of purchase that the App does not work for you. Contact the support channel stated on your Polar receipt with your checkout reference; Polar processes the refund to your original payment method. We may refuse refunds that are abusive (for example repeated purchase-refund cycles), but you always keep the statutory rights described above.
| Situation | Your remedy |
|---|---|
| Changed your mind within 7 days of purchase | Full refund via the support channel on your Polar receipt |
| App does not work on your Device | Full refund within 7 days; also contact support — we can often fix device-specific issues in updates |
| Accidental double purchase | Full refund of the duplicate — contact support with both references |
10. Functionality, permissions and device compatibility
The App reproduces the iPhone’s Dynamic Island experience on Android. To work, it requires the standard Android permissions described in our Privacy Policy (notification listener access and “display over other apps”), which you grant and can revoke in Android settings. Revoking them disables the related features. You acknowledge that:
- Android device manufacturers ship different system skins and battery optimisation strategies; aggressive battery savers or task killers may limit background behaviour, and the App’s documentation explains how to exclude it;
- functionality may vary between Devices, Android versions, and manufacturer restrictions, and we do not warrant that every feature will work identically on every Device;
- major OS updates may temporarily require an App update, which we will supply through the distribution channel used for your purchase;
- the App is a productivity/customisation tool; it is not a medical or safety device, and notification delivery may be delayed or suppressed by the operating system or by other apps.
11. Updates and changes
We may release updates, patches and new versions of the App and may add, change or remove features over time. Updates for the App are distributed through the channel used for your purchase. If we make material changes to these Terms, we will publish the new version on this page with a new “Last updated” date and, where the change is significant, announce it on the Website. Your continued use of the App or Website after a change takes effect constitutes acceptance; if you do not agree with a change, your remedy is to stop using the Website and to uninstall the App.
12. Intellectual property and trademarks
The App and the Website, including their design, code, text, graphics and the Trisle name, are protected by copyright and other rights and remain the exclusive property of the Operator. Nothing in these Terms transfers ownership of anything to you.
Apple, iPhone, iOS, Dynamic Island, Android and Google are trademarks of Apple Inc. and Google LLC respectively. Trisle is an independent product and is not affiliated with, endorsed by, or sponsored by any of these companies. References to their products are descriptive only.
13. Third-party services and links
The Website and purchase flow rely on independent third parties: Polar for checkout, payment, taxes and refunds; Google Analytics (only if you consented — see the Privacy Policy) for aggregate statistics; and GitHub Pages for hosting. Those services are governed by their own terms and privacy policies, and we are not responsible for their content or behaviour. Links to third-party sites are provided for convenience and do not imply endorsement.
14. Disclaimer of warranties
The Website and the App are provided “as is” and “as available” without warranties of any kind, whether express or implied, to the maximum extent permitted by law — including implied warranties of merchantability, fitness for a particular purpose and non-infringement. We do not warrant that the Website will be uninterrupted or error-free.
This does not affect mandatory statutory rights. If you are a consumer in the EU, the UK, or another jurisdiction with mandatory consumer protection, you keep the statutory rights that cannot be excluded, including your rights in respect of non-conforming digital content under the EU Digital Content Directive (2019/770/EU): the App must be conform to the contract, be updated as necessary, and be supported for the period required by law.
15. Limitation of liability
To the maximum extent permitted by law, our aggregate liability arising out of or in connection with the App or the Website is limited to the amount you actually paid for the App (€5.99).
Nothing in these Terms excludes or limits liability that cannot be excluded under applicable law, including: liability for intent or gross negligence; liability for death, personal injury, or damage to health caused by negligence; liability under mandatory product liability law; and, where you are a consumer, liability for damages from injury to life, body or health and for breaches of material contractual duties (cardinal obligations) caused by simple negligence — in the latter case limited to the foreseeable damage typical for this type of contract.
16. Indemnification
You agree to indemnify and hold us harmless from claims, damages and reasonable legal costs arising from your breach of these Terms or your unlawful use of the App or Website, provided that you are responsible for the breach. This does not apply where you are not at fault, and it does not limit any mandatory statutory rights you have as a consumer.
17. Term and termination
These Terms and the license remain in effect until terminated. The license terminates automatically and immediately if you breach the restrictions in section 6. You may terminate at any time by uninstalling the App. Upon termination you must stop using and delete all copies of the App. Sections 12 (intellectual property), 14 (warranty disclaimer), 15 (liability), 16 (indemnification) and 19 (miscellaneous) survive termination. Termination does not affect your refund rights under section 9.
18. Governing law and jurisdiction
These Terms are governed by the laws of the country in which the Operator has its principal place of business, excluding its conflict-of-laws rules and the United Nations Convention on Contracts for the International Sale of Goods.
Consumer protection. If you are a consumer and the law of your country of residence grants you mandatory protective provisions (including the consumer jurisdiction of your local courts) that cannot be waived, you keep the benefit of those provisions and forums, and nothing in these Terms deprives you of them. Mandatory consumer rights under EU law — including the rules of Regulation (Rome I) on applicable law for consumer contracts — always prevail over this choice of law.
19. Miscellaneous
- Severability. If any provision is held invalid, the rest of the Terms stays in force and the invalid provision is replaced by a valid one that comes closest to its economic purpose.
- No waiver. Our failure to enforce a provision is not a waiver of it.
- Assignment. You may not transfer this agreement; we may transfer it in connection with a merger, acquisition or sale of assets, with notice to you and without reducing your rights.
- Entire agreement. These Terms (with the incorporated Privacy Policy) are the entire agreement between you and us regarding the App and Website.
- Language. These Terms are concluded in English; any translation is for convenience only and the English version governs.
20. Changes to these Terms
We may amend these Terms prospectively at any time. The version published on this page at the time of your purchase or use applies. Where an amendment materially reduces your rights, we will not apply it retroactively to purchases already made, and — where required by law — we will seek your explicit agreement before it applies to you.
