Privacy Policy
Last updated: November 1, 2026
Rent Day is designed to run entirely on your device. This policy explains how your data is handled — in short: we collect nothing. Rent Day is developed by Shoumeng Jiaye.
Core principles
We collect almost no data. · No account, no sign-up, no server backend · No analytics or ads — only anonymous crash reports (Sentry) when the app crashes · Rent records and tenant details stay in the device's local database only
Contents
1. Information we collect
1. Your records (properties and rooms, leases, bills, meter readings, tenant and contact details, notes, settings) are stored only on your device and never uploaded to any server. 2. Rent Day has no account system; we do not collect email addresses, phone numbers or other identity information. 3. The only data that leaves your device: anonymous crash reports (stack traces, device model, OS and app version, crash time) sent to Sentry when the app crashes. The app embeds no analytics or advertising SDKs.
2. How information is used
Data is used only to render the app's features on your device. We do not profile, analyze or sell any user data.
3. Storage and security
All data is kept in a local database on your device. Files produced by CSV export are yours to keep; uninstalling the app deletes everything — no copies exist on any server.
4. Third-party services
Rent Day integrates no third-party analytics or advertising SDKs and connects to no servers. When the app crashes, an anonymous crash report (containing no record content) is sent to Sentry (sentry.io). Bill and lease reminders are delivered by the operating system, with content generated on your device.
5. Permissions
Notification permission is used only for the bill and lease reminders you configure in the app, and can be turned off any time in system settings.
6. Data you choose to share
Exports (CSV files) and copied text (rent reminders, listing copy) are generated on your device and leave it only when you actively send them.
7. Deleting your data
Delete individual records in the app, or uninstall the app to erase everything — no copies exist on any server.
8. Children
Rent Day is not directed at children and offers no social or communication features.
9. Changes and contact
If this policy changes, the new version will be published on this page with an updated effective date. Contact: tzhh0617@gmail.com
