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.

🔒 End-to-end encrypted
📱 Stored on your device

Frequently Asked Questions

How is this different from Daylio or Bearable?
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.
Can I track more than just mood?
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.
Is this a replacement for therapy or professional help?
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.
Is Quanitya really free?
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.
Do I need to create an account?
No. Quanitya uses anonymous authentication. You get a recovery key when you start — no email, no password, no personal info required.
Is my data really private?
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.
Does it work offline?
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.
Can I sync across devices?
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.
Can I export my data?
Yes. You can export all your data as JSON at any time. Your data belongs to you.
