1. Introduction Welcome to Days, a calendar and to-do app from an independent developer for personal everyday planning. The app is free to use, requires no account, and contains no in-app purchases. It is supported by third-party advertising.

By installing or using this app you confirm that you have read, understood, and agreed to this document. If you do not agree, please do not install or use the app.

Do not reverse-engineer, crack, or redistribute the app. 2.3 Your data, your ownership Everything you create inside the app — events, to-dos, settings — belongs to you. Your calendar and to-do content is never uploaded to our servers, shared, or sold.

2.4 Disclaimer The app is provided “as is”. We do not guarantee it is bug-free or always available. To the extent permitted by law, we are not liable for any direct or indirect loss arising from your use of the app.

2.5 Service changes We may update or discontinue the app in the future. Significant changes will be announced via in-app notice or release notes.

1. Privacy Policy 3.1 What stays on your device Your app content stays local:

Events, to-dos, birthdays, anniversaries, notes, and settings Stored via Apple SwiftData (local database), optionally synced through your own iCloud account Sandboxed and encrypted by iOS Uninstalling the app deletes all local data We never read or upload the contents of your events or to-dos.

3.2 What is sent to third parties To keep the app free and reliable, Days integrates the following third-party SDKs from Google. They collect limited technical data — not your event or to-do content.

SDK Purpose Data collected Firebase Analytics Anonymous usage analytics (which screens are opened, feature usage) App-instance ID, device model, OS version, country, coarse event counts Firebase Crashlytics Crash and performance reports so we can fix bugs Crash stack traces, device model, OS version, app version Google AdMob Splash and banner ads Advertising identifier (only if you allow tracking), device info, coarse location (country), ad interaction events 3.3 Tracking domains The SDKs above may connect to:

googleadservices.com googlesyndication.com doubleclick.net 3.4 App Tracking Transparency (ATT) On first launch (or before the first ad request) iOS will show the system Allow Tracking prompt.

Allow — AdMob may use your advertising identifier (IDFA) to show more relevant ads. Ask App Not to Track — no IDFA is shared. You will still see ads, but they will be less relevant (contextual only). The app remains fully usable. You can change your choice anytime in iOS Settings → Privacy & Security → Tracking, and review Google’s advertising controls at https://adssettings.google.com.

3.5 System permissions Permission Why When Notifications To push the reminders you set When you turn on notifications, or first create an item with a reminder Tracking (ATT) To request use of IDFA for ad personalization Before the first ad loads We do not use: camera, photos, contacts, microphone, location services, health, motion.

3.6 Children’s privacy Not targeted at children under 13. We do not knowingly collect data from children.

3.7 Region Days is distributed to overseas (non-mainland-China) App Store regions only.
