Privacy policy

STAR ALARM ("the app") is run by Werner Technology. This is what the app handles and how.

Accounts (optional)

Alarms work without signing in. On first start the app gets a random ID for this device; the server keeps only its hash.

If you sign in under Settings › Account (with Apple, Google, or a code sent by email), your alarms and settings are backed up and can be moved to another iPhone or Android phone. The server then keeps the account ID of the service you signed in with, your verified email address (which may be an Apple "Hide My Email" address) and the backup of your alarms and settings. No passwords are handled.

What the server keeps

• The app's language
• The name and reading you enter, and the voice and video clips that say it
• Photos you upload (of a face), and the videos, voices and scripts made from them
• Notices (review started, ready…) and which messages were played
• A hash of the connecting IP address, to limit abuse (the address itself is not kept)
• To count users: your device's ID and how you use the app. The device ID (the Android ID, hashed on the device before it is sent, and kept only as a further hash), the days you opened the app and how many alarms you stopped and snoozed those days, the app's version and language, and your approximate country. A signed-in device counts as its account. Never linked to the advertising ID
• To count users: identifiers and usage. The ID the app makes when first opened and your device's ID (such as the Android ID, hashed on the device before it is sent), kept only as further hashes; the days you opened the app and how many alarms you stopped and snoozed those days; the app's version and language; your approximate country. When you sign in, the device's record is merged into your account. They are never linked to the advertising ID
• If you sign in: the account details above and your backup

If you don't sign in, your alarm times and settings stay on your phone and are never sent. The app uses no analytics tools.

Your gender (if you answer) and your country are used on your phone only, to pick the AI character shown to you, and are not stored on the server. The country comes from Google Play, the SIM or the mobile network; failing those, from the approximate country of the connecting IP address, which Cloudflare tells the server and the server returns without keeping it; failing that, from the time zone.

How it is used

Only to make the voices and videos that wake you, and to deliver them to your phone. A caller made from your photo is shown to no one but you. Photos are reviewed before they can be used.

Services we use

• OpenAI (GPT-6 Luna): writing the messages' scripts (it gets the role and the language, and your name if you chose to be called by it; never your photo)
• DeepSeek: writing a script when OpenAI could not (it gets the same)
• Google Cloud Text-to-Speech: reading the scripts and your name aloud
• Vast.ai GPU servers: making the lip-synced videos from a photo and a voice; each server is destroyed when its work is done
• Vultr (Tokyo): the app's server
• Cloudflare: carrying the connections to the server (it handles the connecting IP address)
• Apple and Google: signing in (only if you sign in)
• Amazon SES (Tokyo): sending sign-in codes by email

Ads

The app shows Google AdMob ads at the bottom of Home. To serve and measure ads and prevent fraud, AdMob collects device identifiers such as the advertising ID, approximate location (from the IP address) and which ads were shown or tapped (Google's policy). Where the law requires it (the EEA, the UK, some US states), you are asked for consent first and can change it any time in Settings › Ad privacy options. On iPhone the app first asks to track you (Apple's App Tracking Transparency); only if you allow it may the advertising ID (IDFA) be used for ads across other companies' apps and websites (tracking). Ads are shown either way, and you can change your answer any time in Settings › Privacy & Security › Tracking. On Android you can reset or delete the advertising ID in your phone's settings. No ads are shown on the ringing screen.

How long, and deleting

Until you delete it. In the app, Settings › Delete all my data (Delete account when signed in) removes this device's or your account's data, the backup included, from the server at once; signing out keeps the account and its backup; photos and your name can also be deleted one by one. Backups keep it for up to 14 days. See Deleting your data.

Photos

Upload only photos of yourself, or of someone who agreed to it.

Children

The app is not meant for children under 13.
