DAYS for iPhone

Privacy Policy

Effective October 21, 2026

DAYS is designed to work without an account, advertising, analytics, or a DAYS server. Everything you enter is stored by the app on your iPhone. The app makes one network request, described below, and it carries nothing you have written.

Information stored on your device

When you create a countdown, DAYS stores the information needed to provide it: a unique identifier, title, date, time-zone reference, category, repeat setting, reminder choice, optional notes, and created and updated dates. DAYS also stores app preferences such as whether reminders and app lock are enabled.

If you add a photograph to a countdown, the image is resized and saved as a file in the same local container. If you write a journal entry about how a day went, that text is stored alongside the countdown. Neither is sent anywhere.

Choosing a photograph uses Apple’s photo picker, which runs outside the app. DAYS never requests access to your photo library and cannot see it; it receives only the single image you pick.

This information is stored in the app’s local data container on your iPhone, with iOS file protection applied so it is encrypted at rest with your device passcode. DAYS does not provide an account, cloud sync, export, or a backend service.

Data collection and tracking

The developer of DAYS does not collect the content of your countdowns, photographs, journal entries, or app preferences. The released app contains no advertising SDK, no analytics SDK, and no third-party tracking SDK, and there is no mechanism in the app capable of transmitting this information to the developer or to another company.

DAYS does not track you across apps or websites and does not sell personal information.

The one network request DAYS makes

When you open DAYS, it requests a single file from heisenbergletmecook.github.io to find out whether a newer version of the app has been released. This is so the app can tell you an update is available, and so that a release later found to be harmful can be stopped from continuing to run.

The request sends nothing about you: no name, no account, no device identifier, no countdown, no photograph, and no app preferences. It has no body and sets no cookies, and the app stores nothing from it except the time it last asked. The response is a short file listing version numbers.

As with any request to any website, the server hosting that file can see that a request arrived from an IP address. The site is GitHub Pages, and GitHub’s handling of its own server logs is governed by GitHub’s privacy statement. No identifier is sent that could connect that request to you or to anything in the app.

If the file cannot be reached — you are offline, the request times out, or the file is missing or unreadable — DAYS treats the result as “up to date” and continues working normally. The check never prevents the app from opening because it failed.

Crash reports

DAYS contains no crash-reporting or analytics code, and writes no diagnostic files to your iPhone.

If you have turned on iOS's own “Share iPhone Analytics” and “Share With App Developers” settings, Apple may send the developer aggregated crash statistics. That is an Apple setting, controlled by you in iOS Settings → Privacy & Security → Analytics & Improvements, and it is not something DAYS requests, switches on, or can see into.

Notifications

If you turn on reminders, DAYS asks iOS for notification permission. The app schedules local notifications on your device. A pending notification contains the countdown title and a short reminder message. It is delivered by iOS without a DAYS server.

Your notification preview may be visible on the Lock Screen depending on your iPhone notification settings. You can change permission or preview behavior in iOS Settings.

Face ID, Touch ID, and device passcode

If you enable app lock, DAYS asks Apple’s Local Authentication system to verify you with the authentication method available on your device. Biometric matching is handled by iOS. DAYS receives only whether authentication succeeded; it does not receive or store your face, fingerprint, optic, or passcode data.

Backups

DAYS does not perform cloud sync. However, its local app data may be included in an iPhone backup managed by Apple, depending on your device and backup settings. Apple’s handling of backups is governed by Apple’s policies and your Apple account settings.

Deleting your data

You can delete one countdown from its edit screen, or use Settings → Privacy → Erase All Data to remove all countdowns and cancel their pending reminders. Deleting the app removes its on-device app data. Copies may remain in device backups until those backups are replaced or deleted through Apple’s backup controls.

Apple services

DAYS uses Apple frameworks for local storage, notifications, device authentication, and photo selection. Apple may separately process App Store, diagnostic, or backup information under Apple’s own policies and your device settings. DAYS does not include a third-party analytics or crash-reporting service, and does not operate a server of its own.

Changes to this policy

If a future version changes how DAYS handles data, this policy will be updated before those practices are represented here. The effective date at the top shows when this policy was last revised.
