RentBook — questions, answered
Is RentBook free?
Yes — RentBook is free to download. The free version is supported by ads, and an optional one-time/Pro upgrade removes them and unlocks extra capacity.
Does RentBook work offline?
The core features of RentBook work offline. Some features use the internet (see the privacy policy for exactly what and why), but your personal content is not uploaded unless a feature explicitly requires it.
Do I need an account to use RentBook?
No. RentBook requires no account, email, or sign-up — just install and start.
Is RentBook safe and private?
RentBook stores everything — your properties, tenants, ledgers, payments, and any documents or photos you attach — locally on your device. There is no account and no Zentryx server, so your tenants’ details never leave your phone except when you choose to share a receipt. On the free tier the app may show ads via Google AdMob. You can read the full RentBook privacy policy at rentbook/privacy.
How do I delete my RentBook data?
Delete individual records inside the app, overwrite everything by restoring a backup, or uninstall the app to remove all locally stored data. Backups or receipts you exported elsewhere stay under your control. To opt out of personalised ads, reset or delete your advertising ID in Android Settings → Privacy → Ads.
