Lemvo1. The short version
- Lemvo Technologies works fully on your phone. You do not need an account.
- If you sign in, your records are stored on our servers in India (Amazon Web Services, Mumbai) so your phones and your family stay in sync.
- Notes, names, addresses and other text you type are encrypted on your phone before they are sent. We cannot read them.
- Your SMS messages and cycle tracker records never leave your phone.
- No ads. No third-party analytics. We do not sell your data.
2. What stays on your phone
- Everything you record: income, expenses, accounts, daily items, LPG, bills, fuel, rent.
- Cycle tracker records, kept in a separate file, never sent, never shared, never exported.
- Your PIN, stored only as a salted hash.
- Android's automatic backup to Google Drive is turned off for Lemvo Technologies.
3. What we receive if you sign in
- Your name and email address from Google (never your password).
- Your phone's name, model, app version and an ID the app creates, so you can manage your devices.
