Tillwhen is a countdown app with home-screen widgets published by Southwest Blueprints. This policy explains what happens to your information when you use it. Contact: info@southwestblueprints.com.

The short version

We do not collect, store, sell or share any of your data. We have no servers and no accounts.
No analytics, advertising, tracking or crash-reporting software.
The app does not have Android's internet permission and opts out of Android's automatic cloud backup.

What the app stores, and where

Your events (titles, dates, emoji, colours, repeat and reminder choices), any background photos you pick, and your settings are stored in the app's private storage on your device.

What leaves your device

Only what you send. If you back up or export, Android's Save dialog lets you choose where the file goes, for example your device, Google Drive or Dropbox. A backup can be protected with a passphrase (AES-256-GCM, with the key derived from your passphrase by Argon2id). We cannot recover a forgotten passphrase.

Calendar (.ics) and CSV exports are plain files and are not encrypted. If you turn on event reminders, your device schedules it. Nothing is sent from a server.

Photos and widgets

If you choose a background photo, Android's photo picker hands the app a copy of just that photo. The app can't see the rest of your photos and needs no photo permission. The home-screen widgets draw from the same data on your device; nothing is fetched or sent.

Purchases

The optional one-time unlock is sold through Google Play. Google processes the payment under its own privacy policy. We do not receive your name, email address or payment details.

Your control

Delete events in the app, or uninstall the app or clear its storage in Android Settings to delete everything. Backup and export files you saved elsewhere stay under your control.

Children

The app is not directed at children and collects no personal information from anyone.

Changes

If this policy changes, we will update this page and its effective date. Because the app has no internet access, it cannot change what it collects without an app update that you install.

iPhone version: the same privacy rules

The Android-specific permission and backup references above describe the Google Play version. The iPhone version has no application networking code, developer backend, analytics, advertising, tracking or crash reporting. iOS has no Android-style internet permission switch. Apple processes the optional one-time purchase under its own privacy policy.

Private app-data directories are marked as excluded from device backups. Manual exports and backup files go where you choose through Files or the share sheet, including a cloud provider you select. Those exported files remain under your control. Delete the app, not Offload, to remove local data.

Photos, documents and text recognition, where available in this app, are processed on the device. Face ID and device passcodes, where used, are handled by the operating system. Reminders are local notifications, not messages from our servers.

Widgets read a local App Group snapshot and copies of selected background photos. Configurable widgets require iOS 17 or later. iOS controls their refresh timing.
