Privacy policy

Last updated: 6 November 2026

1. Who we are

AlibiLock is an agreement documentation app developed and operated by HKSolutions. Contact: support@needsolutions.net

2. What we collect

Account holder (Party A)

• Full name
• Email address
• Your Google account ID, if you sign in with Google
• The signature you draw on an agreement, and when you signed
• Your IP address when you sign
• App version (user agent) and basic device information when you sign
• App language and theme preference
• Notification identifier (to deliver push notifications)
• Purchase status (subscription or credit balance)

Person confirming an agreement (Party B)

Party B does not need an account. We record only at the moment of signing:

• The name they enter
• The signature they draw
• IP address
• Browser (user agent) and basic device information
• Time of confirmation
• Version of the notice they accepted

For both parties, depending on the agreement

• Agreement text, amount, currency, due date
• Photos, if added
• Location, only if separately permitted

Location permission is optional; the app works normally without it. Location (EXIF) data is automatically stripped from uploaded photos.

3. Why we collect it

The sole purpose is to record what both parties agreed to, in a form that cannot be altered afterwards. IP address, device information and timestamps form the evidence trail showing who confirmed the document and when. Without this data the app cannot serve its purpose.

4. Who we share with

We do not sell your data and do not use it for advertising. Sharing is limited to what the service needs:

• Hetzner Online GmbH (Germany): the servers that run the service
• Hetzner Online GmbH (European Union): encrypted backups on a Storage Box, at a different location from the servers
• Google Play: purchases and subscriptions
• Google Firebase: notification delivery
• Google sign-in: only if you choose this method, to verify your identity
• Email server: sending documents and reminders
• Legal requirement: upon a lawful request from a competent authority

The agreement document you create is, by its nature, shared with the other party.

5. Verification page

The QR code on the document leads to a public verification page. That page shows only whether the document is valid, the sealing time, and masked names. The agreement text, amount, signature image and IP address are not shown there.

6. How long we keep it

Sealed agreement records are kept for a default of 10 years, so they remain useful as evidence. If your account is deleted, your account details are removed; sealed documents remain intact, because the other party has an interest in them too.

Encrypted backups are also kept with the same provider, at a different location from the servers. Deleted data drops out of them within 30 days.

7. Security

All connections use TLS. Photos, signature images and documents are stored encrypted. No sealed signature can be deleted. Sealed agreement records cannot be modified or deleted; each record is cryptographically linked to the previous one.

8. Your rights

To access, correct or delete your data, or to request a copy, write to support@needsolutions.net. We respond within a reasonable time.

You can delete your account yourself in the app, under Settings > Delete my account. Without the app, follow the steps at https://alibilock.imitasyonzeka.com/account-deletion, which also lists what is deleted and what is kept.

9. Children

AlibiLock is not intended for anyone under 18.

10. Changes to this policy

If this policy changes, the date on this page is updated; for significant changes we also notify you in the app.

11. About legal status

AlibiLock produces an evidentiary record of what the parties agreed. The document it produces is not a qualified electronic signature and does not replace notarisation.
