Terms of Use — ProofPocket

Effective date: July 27, 2026
Last updated: July 27, 2026

1. General terms

These Terms of Use (the "Terms") govern your use of the ProofPocket mobile app (the "App") provided by KJLabs Studio ("Provider", "we", "us").

Contact for App matters: kjlabs.studio@gmail.com.

Website: https://kjlabs.studio/.

By using the App or purchasing ProofPocket+, you accept these Terms. If you do not accept them, do not use the App or purchase a subscription. Our processing of personal data is described in the Privacy Policy.

These Terms do not limit mandatory consumer rights. Where they conflict with mandatory law, that law prevails.

2. What ProofPocket is

ProofPocket is a tool for personally storing proofs of purchase and warranty information. Depending on the App version, it includes in particular:

  • adding photos of receipts, invoices and nameplates;
  • importing PDF documents, including through the system share sheet;
  • OCR performed on-device and optional cloud OCR/AI services;
  • recording product, purchase, brand, serial-number, order-number, price, note and warranty data;
  • searching the archive and receiving warranty-expiry reminders;
  • optional accounts, data and document synchronisation;
  • where activated in the relevant App version, shared spaces and invitations; and
  • the optional paid ProofPocket+ entitlement.

ProofPocket is not an accounting, legal, tax, financial or warranty service. It is also not a backup service that relieves you of maintaining your own copies of important documents. We do not guarantee that OCR, AI, warranty calculations, reminders or document reading are complete or error-free. Check results and keep original documents when they are needed for a claim, accounting or legal proceeding.

3. Technical requirements and availability

To use the App, you need a compatible iOS or Android device and operating system. An internet connection and an account with the relevant store may be needed for accounts, synchronisation, cloud PDF import/OCR, optional AI, purchases, purchase restoration, sharing and push notifications.

The core local archive is designed to work offline and without an account. We do not guarantee continuous availability of features that depend on third-party services, networks, the operating system, Apple, Google, Supabase, RevenueCat, Firebase or Mistral AI.

4. Account and security

An account is optional for the core local archive. An account may be created or used with email, Apple or Google. You are responsible for providing accurate data, protecting your device and sign-in credentials, and activity taken through your account, unless it resulted from our security breach.

We may require email confirmation. Promptly report suspected unauthorised access to kjlabs.studio@gmail.com.

5. Documents, user content and OCR

You retain rights to your content. To provide the service, you grant us a non-exclusive, royalty-free authorisation, limited to the period during which you use the service, to store, technically process, synchronise and display your content only as necessary to operate the App.

You represent that you have the right to add, store, process through OCR/AI and, if you choose, share content in the App. You must not add unlawful content or content that infringes another person's privacy, copyright or other rights.

Text and data extracted through OCR or AI may be inaccurate. Always verify, in particular, amounts, dates, merchant, serial number, order number, warranty terms and expiry date. See the Privacy Policy to learn when a PDF, OCR text and metadata may be processed by a cloud AI service.

6. Synchronisation and data deletion

After you sign in, the App may synchronise archive data and documents between devices. Synchronisation requires a network connection and may be delayed or fail. Make sure important changes have synchronised before changing devices or signing out.

You may delete an item or document in the App. You may also start account deletion in Settings. Account deletion removes account and synchronised data as described in the Privacy Policy, and local data on the device from which the process was started will also be deleted. Account deletion does not cancel a subscription purchased through the App Store or Google Play.

ZIP/archive export is not currently an App feature. Do not assume the App provides an export of the entire archive until that feature is expressly made available and described in the App.

7. Shared spaces

This section applies only where shared spaces are activated in the relevant App version.

A space owner may invite other eligible people to jointly use the archive in that space. By adding content to a shared space, you understand that authorised members may see its data and documents and, depending on their assigned role, may add, change or delete content.

Creating, joining or writing to a shared space requires an account and active ProofPocket+ for the participant. If an entitlement expires, shared data remain available to read to the extent provided by the App, but writing may be blocked. Leaving a space, removing membership or deleting a space remains available according to the permissions in the App.

An invitation link or token may allow its recipient to see information about a space and join it if they meet the requirements. Do not share it publicly or with unauthorised people. Invitations expire after the period shown in the App (currently, generally after 7 days) and may be revoked by the owner through the available options.

Space owners and managers are responsible for selecting members and ensuring that content sharing complies with the law. Members should resolve disputes, including disputes about content added to a space, directly with one another. We may take technical action necessary to protect the App, its users and legal compliance.

8. ProofPocket+ and in-app purchases

ProofPocket+ is a renewable subscription entitlement where such an offer is shown in the App. The free plan allows up to 5 active personal items; "active" means an item that has not been deleted. ProofPocket+ removes this limit and unlocks the shared-space features described in section 7 when available.

The store and purchase screen show the price, currency, billing period, free trial terms and automatic-renewal details before you confirm a purchase. A subscription renews automatically unless you cancel it under the App Store or Google Play rules before the deadline set by that store. Purchase management, cancellation, refunds and billing are subject to Apple's or Google's terms and mandatory consumer law.

You may use the "Restore purchases" feature when it is available. A temporary purchase-verification issue should not remove access to your existing local data. Expiry of ProofPocket+ does not block viewing, searching, editing, deleting or recovering personal data already stored by you.

Where the law requires separate, express consent to begin a digital service before the withdrawal period ends, and acknowledgement of the loss of the withdrawal right, we will request it in the relevant purchase flow. These Terms do not themselves replace that consent and acknowledgement.

9. Acceptable use

You must not:

  • interfere with the operation, security, limits or interfaces of the App;
  • access other users' data without permission;
  • use the App unlawfully, fraudulently, in a way that infringes third-party rights or threatens security;
  • reverse engineer, decompile or circumvent protections to the extent prohibited by law, except where mandatory law expressly permits it; or
  • distribute invitation tokens or shared-space data without permission.

We may restrict or suspend access to an account or feature where necessary and proportionate if we reasonably believe that you have breached these Terms, the law or App security. Where permitted by law and security, we will tell you the reason and how to appeal.

10. Liability

To the extent permitted by law, the App is provided "as is" and "as available". We do not guarantee uninterrupted availability or error-free OCR/AI results, document data, synchronisation, warranty calculations or notifications.

We do not exclude or limit liability that cannot lawfully be excluded or limited, including liability to a consumer for a lack of conformity of digital content or a digital service. Nothing in these Terms excludes liability for intentional misconduct, gross negligence, death or personal injury where applicable law prohibits that exclusion.

11. Intellectual property

Subject to your rights in your content, the App, its code, brand, graphics and other elements are protected by law. You receive a personal, revocable, non-exclusive and non-transferable licence to use the App in accordance with these Terms and the rules of the store from which you downloaded it.

12. Changes to the App and Terms

We may develop, change, withdraw or add App features for legitimate technical, security, legal or business reasons. If a change materially affects the digital service or your rights, we will provide the notice and remedies required by law.

We may change these Terms for legitimate reasons, including changes in law, features, security or billing. We will publish the new version with its effective date. Where required by law, we will notify you in advance and allow you to stop using the service before the change takes effect.

13. Complaints and consumers

Send complaints about the App to kjlabs.studio@gmail.com. Please include a description of the issue, the App version and contact details needed to reply. We will acknowledge and respond to the complaint within the time required by applicable law.

If you are a consumer habitually resident in the European Economic Area, you also benefit from mandatory consumer-protection rules in your country of habitual residence.
