FAQ
Fair questions, straight answers.
Does it really work without the internet?
Yes. Everything works offline: adding entries, budgets, bills, reports and saving backup files. Your money data is kept on your phone, encrypted. The app goes online only for extras you choose: cloud backup, exchange rates and the assistant download.
Where is my data stored?
On your phone, encrypted with AES-256 using a key made from your passcode. If you turn on cloud backup, an encrypted copy also goes to a Budget Lock folder on your own Google Drive, and Google sees only ciphertext.
What if I forget my passcode?
Use your recovery key, which you can make in App lock. Without the passcode or the recovery key, nobody can open the data, including us.
I use the free Budget Lock app. Can I bring my data?
Yes. Save a backup file in Budget Lock, then tap "Restore from backup" when you first open Pro. Your accounts, entries, budgets and settings come across.
How do I move to a new phone?
Save a backup file and copy it to your new phone, or use cloud backup. Install Budget Lock Pro there and restore it with the same passcode.
Is there a subscription?
No. You pay once on Google Play. There are no ads and no in-app purchases.
Does it sync between my devices?
No, by design: there's no server of ours. Use a backup file, or cloud backup to your own Drive, to move your data between phones.
Which languages and currencies does it support?
49 languages and any currency, with Indian lakh and crore formatting.
Do you collect any data?
Not your money data. There's no account, no analytics and no ads. A few optional features use the internet, and the privacy policy lists exactly what each one sends.
Is my money data safe if I lose my phone?
It's encrypted and needs your passcode to open.
