1. Purpose and data on your device

Sack&Pack helps you prepare for travel. It stores trip names, travel dates and categories, personal templates, tasks and packing entries, including notes, areas, priorities, processing windows, due dates and completion status. Random internal identifiers, language and reminder options and delivery/snooze state are also stored. Only enter information about other people where necessary and lawful.

2. Local processing

Data is kept in the app’s private Room/SQLite database and settings. The app requests no internet permission and sends no travel or usage data to the provider. There is no user account, advertising or analytics/tracking service integrated in the supplied code. The provider cannot access your local lists. The app uses no location, camera or contacts permission.

3. Reminders and permissions

Reminders are scheduled locally using Android’s alarm service, without internet push. Android 13 and later request POST_NOTIFICATIONS permission; RECEIVE_BOOT_COMPLETED allows rescheduling after a restart. Notifications may contain task titles and trip names. They are marked private; lock-screen display depends on your Android settings. You can disable reminders in the app or revoke permission in Android.

4. CSV files and backups

Files are read or written only when you request it, using Android’s file picker. No broad storage permission is requested. CSV exchanges individual trips or templates, for example with the local PC editor. The JSON backup contains all trips, templates and entries and the settings described above, including reminder state. It has no additional encryption. You choose the location and any sharing. If you select a cloud document provider, it processes the file under its own terms. This does not create a separate cloud copy with the Sack&Pack provider. Android cloud backup and device transfer are excluded in the manifest or backup rules; use the app’s own backup feature to move to another device.

5. Retention and protection

Local data is retained until deleted. Marking a task complete does not delete it. You can remove trips, templates and entries in the app. Clear Android app storage or uninstall the app to remove all local app data. Exported CSV files, backups and copies must be deleted separately from their respective locations. Saving uses a private temporary file; if the process crashes, this may remain until the cache is cleared. There is no separate app PIN or additional database encryption. Use your device lock and protect your backups.

6. Contact and legal bases

If you contact us by email, your sender address, message and attachments are processed through the email services used to answer your enquiry. The legal basis is Article 6(1)(b) GDPR for contract-related enquiries; otherwise it is the legitimate interest in answering enquiries under Article 6(1)(f) GDPR. Messages are retained as long as needed for handling the enquiry or necessary evidence, subject to statutory retention duties. Technically necessary local storage and access for explicitly requested functions are based on section 25(2)(2) TDDDG. This gives the provider no access to your local data.

7. Your rights

Where the provider processes personal data, you have rights to access, rectification, erasure, restriction, portability, objection and withdrawal of consent for the future, subject to legal conditions. The provider cannot access purely local app data; you manage it yourself. You may lodge a complaint with a data protection authority, particularly the State Commissioner for Data Protection and Freedom of Information Baden-Württemberg (www.baden-wuerttemberg.datenschutz.de).

8. Google Play and external services

When you obtain or update the app through Google Play, Google processes data under its own privacy policy. Websites and email apps opened externally are separate services. This information applies to the native Sack&Pack app and will be updated when data processing changes.
