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
- Most mood trackers store your emotional data on their servers in a way their team can read. Quanitya encrypts everything on your device first. Your mood entries, notes, and patterns are genuinely private — we couldn't access them even if asked to.
- Yes. You can add custom tags for anything — sleep quality, exercise, medications, social activities, energy levels. Over time you'll see how these connect to your mood patterns.
- No. Quanitya is a mood journal and self-tracking tool, not a medical app. It can be a great companion to therapy — many people share their mood trends with their therapist — but it doesn't provide diagnoses or clinical advice.
- 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. Even the paid analysis is privacy-preserving — your data is stripped of all labels and sent as anonymous numbers. The server does the math and sends results back, with nothing stored.
- 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.
- Yes. Quanitya works fully offline. All your data is stored locally. Cloud sync is optional and encrypted end-to-end if you choose to use it.
- Yes. Encrypted cloud sync is available as an optional subscription. Your data is encrypted end-to-end before it leaves your device — the server never sees it in plaintext.
- Yes. You can export all your data as JSON at any time. Your data belongs to you.
