Terms of Service — ProofPocket
1. Who We Are and Acceptance
These Terms of Service ("Terms") govern your use of the ProofPocket mobile application ("App"), operated by KJLabs Studio (https://kjlabs.studio/), contact: kjlabs.studio@gmail.com ("Developer", "we").
By downloading, installing or using the App you agree to these Terms. If you do not agree, do not use the App.
2. What the App Is — and What It Is Not
ProofPocket is a personal, offline-first archive for photos of purchase documents (receipts, invoices, warranty cards) with optional warranty reminders and optional paid cloud sync.
The App is an organizational convenience tool only. In particular:
- The App does not create, certify or guarantee legally valid proof of purchase. A photo or scan stored in the App may not be accepted by a seller, manufacturer, tax authority or court. You are solely responsible for retaining original documents as required by law or by warranty/return conditions.
- Warranty dates, statuses and "days left" values are informational estimates computed from data you entered or from OCR. They are not legal determinations of your warranty or statutory rights.
- OCR (text recognition) is automated and may produce incorrect, incomplete or misleading results (wrong amounts, dates, store names). You must verify all extracted data yourself.
- Reminders and notifications are provided on a best-effort basis. Delivery depends on your device settings, operating system behavior, battery optimization and third-party services. We do not guarantee that any reminder will be delivered or delivered on time, and missing a warranty deadline, return window or any other date remains your responsibility.
- The App does not provide legal, tax, accounting or financial advice.
3. License
We grant you a personal, non-exclusive, non-transferable, revocable license to use the App on devices you own or control, in accordance with these Terms and the applicable app store rules. You may not: reverse engineer the App (except to the extent permitted by mandatory law), redistribute or resell it, use it unlawfully, or attempt to gain unauthorized access to our or our providers' systems.
4. Your Content and Your Responsibilities
- All documents, images and data you store in the App are your content. You retain all rights to it; we claim none.
- You are solely responsible for the legality and accuracy of your content and for how you use it.
- Local data and backups. In the free tier, all data is stored only on your device. You are solely responsible for backups. Uninstalling the App, device loss, damage, OS updates or storage failure may cause permanent, unrecoverable loss of your data. The Developer has no copy and no ability to recover it.
- You are responsible for securing your device and your account credentials.
5. Account
Creating an account (Sign in with Apple / Google) is optional and required only for paid cloud features. You may delete your account at any time in the App; deletion removes synced data from our systems as described in the Privacy Policy. We may suspend or terminate accounts used in violation of these Terms or applicable law.
6. Subscriptions and Payments
- Paid features (e.g. cloud sync) are offered via auto-renewing subscriptions or other purchases processed exclusively by Apple App Store or Google Play under their terms. We do not process payments ourselves.
- Prices, billing periods and trial terms are shown in the App before purchase. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period, via your App Store / Google Play account settings. Uninstalling the App does not cancel a subscription.
- Refunds are handled by Apple/Google under their policies and applicable consumer law. For digital content supplied immediately with your express consent, the EU 14-day withdrawal right may not apply to the extent permitted by law; you will be informed and asked for consent where required.
- We may change subscription prices or features prospectively; changes apply from the next billing period and you may cancel before they take effect.
7. Availability and Changes to the App
- The App and any online features (sync, notifications) are provided without any guarantee of continuous, uninterrupted or error-free availability. Online features depend on third-party providers (Supabase, Google/Firebase, RevenueCat, Apple) whose outages are outside our control.
- We may modify, suspend or discontinue the App or any feature at any time. For paid features, mandatory consumer law remedies (including under the EU Digital Content Directive as implemented in Polish law) remain unaffected.
- We are not obliged to provide support, maintenance or updates beyond what mandatory law requires.
8. Disclaimer of Warranties
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE APP IS PROVIDED "AS IS" AND "AS AVAILABLE", WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, ACCURACY, DATA INTEGRITY OR NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE APP WILL MEET YOUR REQUIREMENTS, THAT OCR RESULTS WILL BE ACCURATE, THAT REMINDERS WILL BE DELIVERED, OR THAT DATA WILL NOT BE LOST.
9. Limitation of Liability
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW:
1. THE DEVELOPER SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL OR PUNITIVE DAMAGES, OR FOR LOSS OF DATA, LOSS OF PROFITS, MISSED WARRANTY OR RETURN DEADLINES, REJECTED CLAIMS, TAX OR ACCOUNTING CONSEQUENCES, OR LOSS OF ORIGINAL DOCUMENTS, ARISING OUT OF OR RELATED TO THE USE OF OR INABILITY TO USE THE APP.
2. THE DEVELOPER'S TOTAL AGGREGATE LIABILITY FOR ALL CLAIMS RELATING TO THE APP SHALL NOT EXCEED THE AMOUNTS YOU PAID FOR THE APP IN THE TWELVE (12) MONTHS PRECEDING THE EVENT GIVING RISE TO THE CLAIM (OR EUR 10 IF YOU PAID NOTHING).
3. THESE LIMITATIONS APPLY REGARDLESS OF THE THEORY OF LIABILITY (CONTRACT, TORT, STATUTE OR OTHERWISE) AND EVEN IF THE DEVELOPER WAS ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
Consumer rights savings clause. Nothing in these Terms excludes or limits liability that cannot be excluded or limited under applicable law, including liability for damage caused intentionally (Art. 473 § 2 of the Polish Civil Code), liability for death or personal injury caused by negligence, and mandatory consumer rights under Polish and EU law (including statutory conformity remedies for digital content and services). If you are a consumer, these Terms do not deprive you of any protection granted by mandatory provisions of the law of your country of residence.
10. Indemnification
To the extent permitted by law, and excluding consumers where such clauses are prohibited, you agree to indemnify and hold the Developer harmless from claims by third parties arising from your content or your unlawful use of the App.
11. Force Majeure
The Developer is not liable for failure to perform caused by events beyond reasonable control, including outages of third-party infrastructure, network failures, acts of authorities, or changes to operating systems and app store policies.
12. Termination
You may stop using the App at any time. We may terminate or suspend access to online features if you materially breach these Terms. Sections that by their nature should survive (including Sections 8–11) survive termination.
13. Changes to These Terms
We may amend these Terms for valid reasons (new features, legal changes, security). The current version is available in the App and/or the store listing. Material changes will be announced in the App in advance where required; if you do not accept them, stop using the App and cancel any subscription before they take effect.
14. Governing Law and Disputes
These Terms are governed by the laws of Poland. If you are a consumer, this choice of law does not deprive you of protection under the mandatory laws of your country of habitual residence, and jurisdiction rules protecting consumers remain unaffected.
Consumers may use out-of-court complaint and redress mechanisms, including assistance from municipal (powiatowy/miejski) consumer ombudsmen and the Trade Inspection (Inspekcja Handlowa) in Poland.
15. Miscellaneous
- If any provision of these Terms is held invalid, the remaining provisions remain in effect.
- These Terms, together with the Privacy Policy, constitute the entire agreement between you and the Developer regarding the App.
- Apple and Google are not parties to these Terms and bear no responsibility for the App; where required by store rules, Apple/Google are third-party beneficiaries entitled to enforce these Terms.
