In short: Battery Guardian checks your phone's battery, apps, data and storage on your phone. To sign in, keep your free months and plan, and (if you choose) share your phone's battery with your family, a small amount of information is kept on our server. We never sell your data and we show no ads.
None of this leaves your phone, except the small family status in section 3 if you join a family.
| Information | Why |
|---|---|
| Your Google account name and email | To sign you in (Sign in with Google). Accounts are kept on our account server at mahajyotish.com. |
| A device identifier (Android ID) | So the 3 free months are given once per phone and once per account. |
| Your plan: free-trial dates, paid-until date, order numbers | To know whether your plan is active. |
| Payment confirmation | Payments are made through PhonePe or Google Play. We receive only the result (paid / not paid, amount, order number). We never see or store your card, UPI PIN or bank details. |
To find what is hard to use and fix crashes, the app sends a small record of how it is used: which screens are opened, which steps (sign-in, plan, family) are finished or stopped, errors and crashes, how fast the app starts, and the app's own battery use. It also sends phone facts: model, Android version, app version, language. It never sends message text, file names, photos, location, or the list of your other apps. It is linked to your account when you are signed in, kept for up to 180 days, and never sold or shared. Turn it off any time in Settings → Help improve the app.
If you create or join a family group, your phone shares with the members of that group only: phone name, battery %, charging, temperature, free storage and when it was last seen. Members can ring your phone if it is lost. You can leave the family at any time, and your status is then no longer shared.
Each permission is asked only when you use the feature that needs it.
We do not sell or rent your information and we do not use advertising or tracking SDKs. Information is shared only with: Google (sign-in, Play billing, push messages), PhonePe (when you pay with it), and the family members you choose.
Account and plan records are kept while your account is active. To delete your account and its data, use Settings → Delete my account in the app, or email vgflexcg@gmail.com. We delete it within 30 days, except payment records we must keep by law.
Battery Guardian is a family app. A child's phone should be set up by a parent, who signs in with their own Google account and decides whether to join a family. We do not knowingly collect personal information directly from children.
All connections use HTTPS. Server access is limited to the people who run the service.
