Your data stays with you
How Vernya keeps your tracking on your device, and what that means in plain English.
Vernya keeps your cycle data on this device only. Nothing is sent to our servers unless you choose to turn on optional smart summaries.
If you turn on smart summaries, we send only de-identified counts and dates from your cycle to our service, which uses Google's AI to write the summary. Your name, birth year, and your written notes are never sent. You can turn it off any time.
You can download a password-locked backup file from Settings whenever you like. Clearing this site's storage in your browser, or removing the app, deletes the local data.
For the curious
Backup files are protected with strong encryption (AES-GCM) using the password you set. Without that password, nobody can open the file - so keep it somewhere you'll remember.
Common questions
Quick answers to questions people often have about this topic.
Does Vernya send my period data to the cloud?
No. Your cycle data stays on this device. The only thing that ever leaves is a de-identified summary, and only if you turn on smart summaries yourself.
Do I need an account?
No. There's no sign-up. Your profile lives on the device you're using.
What happens if I clear my browser data?
Your Vernya data is deleted, because it lives in your browser. If you want a copy you can restore later, download a password-locked backup from Settings first.
How do I move my data to a new phone or computer?
Download a password-locked backup file from Settings on your old device, open Vernya on the new one, and use Restore. You'll need the same password you set when you saved the file.
What if I forget my backup password?
We can't unlock it for you - that's the whole point of strong encryption. Keep the password somewhere safe (a password manager works well).
