Privacy Policy – Academic Calendar

This policy explains how the “Academic Calendar” app (the “App”) handles information. We collect as little as possible, and the App does not require an account or sign-in.

1. Data stored only on your device

The App stores on your device only: your settings (such as language, theme, school calendar region and notifications) and the personal events and payday dates you add yourself. This data is not sent to us and we cannot access it; it is removed when you uninstall the App. It may be included in your device backup if backup is enabled in your device settings, under Google’s policies.

2. Downloading data

The App downloads the school calendar file from GitHub so dates can be updated without an app update. This is a request for a public file only; the App sends no data about you with it. GitHub may log standard technical information such as your IP address under its privacy statement.

When opened, the App also reads public settings files from our website on the same service (sadalogic.github.io): messages from us when needed (such as an update notice, stopping the App, or a general message), turning ads on or off, and promotions for other SadaLogic apps with their images. These are also reads of public files only; the App sends no data about you with them.

3. Notifications

Reminders are scheduled locally on your device and do not use any server. The App asks for notification permission only when you turn notifications on in Settings.

4. Advertising

The App shows ads through InMobi. Through its SDK in the App, InMobi and its partners may collect information such as:

• Advertising ID and device information (such as model, operating system and language).
• IP address and approximate location derived from it (not precise location; the App does not request location permission).
• Ad interaction information (such as impressions and clicks).

This information is used to serve and measure ads and prevent fraud, and is subject to InMobi’s Privacy Policy. You can reset or delete your Advertising ID in your device settings (Settings → Google → Ads, or Settings → Privacy → Ads, depending on your device).

We aim to keep ads family-friendly and apply the strictest content filtering available from InMobi.

The App may show, in the ad space, promotions for other SadaLogic apps labeled “From SadaLogic apps”. These promotions collect no information, and we do not track views or taps. Tapping one opens the app’s Google Play page with a link that states only the source of the visit (this app’s name and the ad position), so Google Play reports show us aggregate numbers of visits and installs, with no data about you.

5. What we do not collect

The App does not collect your name, phone number, email address, precise location, contacts or photos. When you share an event as an image, the image is created on your device and sent through the app you choose.

6. Children

The App is not directed to children under 13, and we do not knowingly collect personal information from them.

7. Email contact

If you email us (for support or feedback), we receive your email address and message, and the technical information if you choose to attach it: app version, device model, Android version, and app and device language. The App shows this information before sending so you can decide whether to attach it, and it is sent from your own email app, not by the App. We use it only to reply to you.

When you use “Report an ad” in Settings, the email also contains the IDs of the last 5 ads shown to you (ad type, ID and display time), so we can block the reported ad with InMobi, along with the technical information if you choose to attach it. These IDs are kept on your device only until you choose to send them; the App shows them before sending, and they are sent from your own email app.

8. Changes to this policy

We may update this policy from time to time; the new effective date will appear at the top of this page.
