Terms of use
Last updated: November 4, 2026
These terms apply to your use of the Mumpad apps, the mumpad.app website and the sync service provided by SyconX LLC (together, “Mumpad”). By creating a Mumpad account or using the app, you accept these terms. How we handle your data is described in the privacy policy.
Only you hold your master password
Mumpad is end-to-end encrypted: your notes and passwords are encrypted on your device with a key derived from your master password. That key never reaches us. As a result:
- If you forget your master password, we cannot recover your data. There is no reset link and no back door.
- Keeping your master password and your device locks safe is your responsibility.
- If you notice access to your account that you did not make, change your master password right away and write to us.
Your account
When you create an account, you must give a valid email address; we send account notices there. You must not share your account or create one on someone else's behalf. You can also use Mumpad without an account, on your device only (local mode); in that case your data never reaches our server.
Your content is yours
Your notes, passwords and everything you add belong to you. You only give us permission to store their encrypted form and sync it between your devices; we cannot see, process or sell your content.
Acceptable use
When using Mumpad, you agree not to:
- use it for unlawful purposes;
- try to disrupt the service, our servers or other users' accounts, or access them without permission;
- send automated requests beyond normal use, or abuse storage as file hosting;
- try to get around security measures such as sign-in attempt limits.
If we see a breach of these rules, we may suspend your sync access or close your account. Where possible, we will tell you in advance and give you time to export your data.
Service continuity and backups
We run Mumpad with care and back up the encrypted data on our server every night. Even so, we cannot guarantee that it will run without interruption or errors. We recommend keeping your important data on one of your devices or in an exported copy as well. If we decide to shut the service down, we will announce it at least 30 days in advance and make sure you can export your data during that time.
Fees
Pricing will be announced separately. If we add a paid plan or feature, its price and terms will be shown clearly before you buy; purchases made through an app store are also subject to that store's terms.
AI features
AI features (for example, correcting the spelling of a note) are off by default and run with your own Anthropic API key; their use and cost are between you and Anthropic. They run only when you explicitly approve. Passwords and password notes are never sent.
Deleting your account
You can delete your account at any time from within the app, or by writing to destek@mumpad.app from your account's email address. Deletion immediately removes all of your encrypted data and sessions from our server and cannot be undone. The data also drops out of nightly backups within 30 days. Local copies on your devices stay there until you remove them.
Limitation of liability
Mumpad is provided “as is”. To the extent permitted by applicable law, we are not liable for indirect damages caused by a forgotten master password, by your device or account being compromised outside our control, or by service interruptions. These terms do not limit the rights you have by law as a consumer.
Changes
We may update these terms. If there is a significant change, we will announce it on the website and in the app at least 14 days before it takes effect. Continuing to use Mumpad after a change means you accept the new terms; if you do not, you can delete your account.
