Where is my data?

On your device, and nowhere else. Invoice Maker has no account and no server. That makes it fast and private, but it also means we cannot recover your data for you if you lose the device.

Backing up

Go to Settings → Backup → Export backup. You get a single file containing every invoice, client and setting, plus your logo and signature. Save it to iCloud, Google Drive, or email it to yourself.

Do this before changing phones, and ideally now. Restoring is Settings → Restore from backup, which replaces everything currently in the app.

Moving to a new phone

1. On the old phone, export a backup and save it somewhere you can reach.
2. Install Invoice Maker on the new phone.
3. Restore from that backup.
4. If you bought the lifetime unlock, open the unlock screen and tap Restore purchase. Use the same Apple ID or Google account.

I paid but the app still shows ads

Open Settings → Unlock everything and tap Restore purchase. You must be signed in with the account you bought it on. If you have just reinstalled and have no signal, connect to the internet once and reopen the app — the unlock is remembered afterwards, including offline.

Will my old invoices change if I change settings?

No. Every invoice keeps the currency, tax rate, business details, logo and design it had when you issued it. Changing your settings only affects documents you create afterwards. This is deliberate: a document you have already sent to a client must never quietly change.

Can I continue my existing invoice numbers?

Yes. Settings → Numbering lets you set the format and the next number, so you can carry on from a paper or spreadsheet series. If a number is already used, the app skips to the next free one rather than creating a duplicate.

Does it work without internet?

Entirely. Creating invoices, generating PDFs, sharing and backing up all work offline. Only ads need a connection, and their absence changes nothing else.
