Terms of Service — Zeif

Last updated: October 15, 2026

1. Acceptance of the Terms

By using Zeif (“the App”) you accept these Terms of Service. If you don't agree with them, don't use it.

2. What the App is

Zeif is a personal organization app that lets you record documents and their expiry dates, vehicles, pets and their vaccines, subscriptions, cards, reminders and notes, and reminds you before something expires. It also lets you share part of that content with a household.

Zeif is a subscription service: using it requires an account and an active subscription. There is no free plan and no guest mode.

3. Your account

To create an account you need an email address, which you will have to verify, and a password. You are responsible for keeping that password secret and for what happens in your account.

You can sign out or delete your account from Settings → Zeif account. We may suspend an account that breaches these Terms, letting you know unless the law prevents it.

4. The recovery code, which is not the password

They are two different secrets, and mixing them up is the most expensive mistake you can make with Zeif:

• The password opens your account. If you forget it, we email you a code and you change it.
• The recovery code decrypts your documents on a new phone. It is generated on your device and never reaches us.

5. Your content is yours

You keep full ownership of everything you store. You grant us only the technical license strictly necessary to store and transmit the encrypted content you choose to sync, and to deliver it to the members of your household when you share it.

That license doesn't allow us to read it, and we couldn't even if we wanted to: the content is encrypted on your device before it leaves. We don't analyze it, we don't train anything with it and we don't hand it over to third parties.

6. Plans, payments and renewal

• Cloud — your documents encrypted in the cloud, for one person.
• Home — the above, plus sharing with up to four people, you included.

Both are offered with monthly or annual billing. They are subscriptions and renew automatically until you cancel them.

• Billing is handled by Google Play and is also governed by its terms.
• You cancel from Google Play, not from Zeif. When you cancel, you keep access until the end of the period you already paid for.
• Refunds are handled by Google under its own policy. We don't process charges or refunds.
• If you change devices, you restore the purchase from the App with the same store account.
• Prices may change. A price change is announced in advance and never applies to a period already paid.

7. What happens if you stop paying

You can no longer enter the App or upload new content.

Your documents are not deleted. They stay encrypted on your phone and on our server, and you can get them back by reactivating the subscription. Charging to give back something that is already yours doesn't seem right to us.

8. The household

• A household is paid for by whoever creates it. Invited members don't need their own subscription while they belong to it.
• You join with an invitation code that expires, and both sides compare a few words before sharing anything.
• Anyone can leave whenever they want, and whoever created the household can remove a member. In both cases the key is rotated: whoever leaves can no longer open what is uploaded afterwards.
• What a member already downloaded stays on their device. We can't delete it, just as we couldn't take back a paper you already handed to them.
• If the person who pays cancels or leaves, the other members lose their covered access.

9. Acceptable use

Don't use the App to:

• Store content that is illegal to possess in your jurisdiction.
• Infringe the rights of others, including the privacy of other people whose documents you store or share without their consent.
• Circumvent the stores' payment mechanisms or share access beyond the seats of your plan.

10. Availability

Zeif depends on our server to sign in, sync and share. Once you are in, the documents already on your phone open offline.

We do what is reasonable to keep the service available, but we don't guarantee it will work without interruption. We may modify or remove features in future versions, and we will never release an update that deletes your data without clearly warning you.

11. Termination

You can stop using the App whenever you want. To delete your account and what we keep, use Settings → Zeif account → Delete account; to delete what is on the phone, Settings → Help → Delete all my data. Uninstalling doesn't delete your account. More detail in data deletion.

Cancelling the subscription and deleting the account are different things: one doesn't do the other.

12. Limitation of liability

The App is provided “as is”. It is a personal organization tool and does not replace professional advice or the official documents you record in it.

To the maximum extent permitted by applicable law, we will not be liable for data loss resulting from the loss or failure of your device, from forgetting your recovery code or your encryption phrases, or for damages arising from an expiry reminder that doesn't arrive in time because of operating system restrictions, battery saving or device settings.

Nothing in these Terms excludes liability that the law does not allow to be excluded.

13. Governing law

These Terms are governed by the laws of Colombia, without prejudice to the rights you have as a consumer in your country of residence.

14. Changes to these Terms

We may update them. Substantial changes will be announced inside the App, and the date at the top will always reflect the latest version.
