Why people switch to Quanitya
Encrypted and on your device
Your data is encrypted and stored locally. The server can't read it — even if someone broke in, they'd get nothing usable.
No account, no email, no password
Sign up anonymously. No personal information collected. We don't know who you are and we like it that way.
Track it your way
Build custom templates with the fields you actually need — or describe what you want and let AI create it for you.
Works offline, syncs when you want
Everything works without internet. Want your data on all your devices? Optional encrypted sync keeps everything in sync — still end-to-end encrypted.
Free forever
All tracking, templates, charts, and local analysis are free with no ads. Cloud sync and advanced AI analysis are optional upgrades.
Source code you can verify
Our code is publicly available. Don't take our word for the encryption — check it yourself.
We can't see your data — even if we wanted to
Your entries are encrypted on your device. If you turn on sync, data is encrypted before it leaves your phone — the server only stores blobs it can't decrypt. We don't collect names, emails, or any personal identifier. We don't even know who you are — just an anonymous public key. If we got hacked tomorrow, attackers would find encrypted noise and anonymous keys. Nothing useful.
Frequently Asked Questions
- Yes. When you set up your water tracker you can choose millilitres or fluid ounces — whichever unit you think in. Your daily goal and every logged entry will use the unit you pick.
- You set a schedule — for example, every 90 minutes between 8 AM and 8 PM — and Quanitya sends a local notification reminding you to drink. Reminders are stored on your device and never routed through external servers.
- Most hydration apps upload your intake data to their cloud in plain text, sometimes sharing it with health platforms or ad networks. Quanitya encrypts your data on your device before it goes anywhere, and if you skip cloud sync entirely, it never leaves your phone.
- Yes. All tracking, templates, charts, and local analysis are completely free — no ads, no paywalls, no hidden costs. Optional paid features include cloud sync and advanced statistical reports.

- No. Quanitya uses anonymous authentication. You get a recovery key when you start — no email, no password, no personal info required.
- Yes. Your data is encrypted on your device and never sent anywhere unencrypted. We use anonymous authentication — no email, no name, no phone number. The server stores only encrypted data it cannot read.
