TAS Shift Planner is developed by Tempo Apps Studio. For privacy or data questions, contact info@tempoappsstudio.com.
Local data
The app stores your shift definitions, schedule, work hours, breaks, rates and supplements, notes, reminders, calendar links, appearance and language preferences in app storage on your device. These local features do not require a TAS account. This app has no Tempo Apps Studio server receiving your planning or earnings calculations. It includes no advertising or analytics SDK.
Connected calendars
If you grant calendar access, the app can list calendars available on your device. You choose which calendars to link. The app reads events from selected calendars. With write access, it can publish your shifts and create, edit or delete appointments in the selected own calendar. Other linked calendars are used as read sources. The app respects access allowed by Android and the calendar provider.
Calendar information can include event titles, dates, times, notes and calendar or account names. For synchronised calendars, the provider processes data under its own terms and privacy policy. The provider also handles sharing and invitations. Disconnecting a calendar removes the app link without automatically deleting its existing events. Explicitly deleting an app-managed event can synchronise that deletion to the provider.
Reminders
The app uses local Android notifications and alarms for reminders you configure. Notification content can be visible according to your device settings. You can change notification permissions, sound and visibility. Battery restrictions and Do Not Disturb can delay or silence notifications.
Backups and sharing
A .tspbak file contains local planning and personal settings, potentially including pay amounts, notes and calendar links. It is not encrypted; its integrity check is not password protection. Store it only in a location you trust. For manual backups, you choose where to save or open the file using the Android file picker. If you select a cloud storage provider, its terms and privacy policy also apply.
From version 0.1.4, you can also enable automatic local backups. These are off by default. You choose a shared folder on your device and grant persistent read and write access to that folder through Android. The app saves copies in the TAS Shift Planner subfolder, daily or weekly; Android may delay the scheduled time. You can disable the feature or revoke folder access. The app does not automatically delete completed copies, which remain outside app storage after you uninstall the app.
The app verifies that a local copy has been written and read back. This does not prove cloud upload. For automatic upload to your own cloud, you separately configure a suitable sync app or cloud feature; that service processes the files under its own terms and privacy policy. Through this local-folder route, TAS Shift Planner does not receive cloud login credentials or perform the cloud upload itself. Check the upload and retention of recovery copies yourself. After reinstalling, you must select the local backup folder again and explicitly enable automatic backup.
External calendar appointments, purchase and licence rights, and widget placement are excluded from the backup. Shift-library export lets you choose whether to include pay settings. When sharing, you choose the receiving app or person. Exported files and backup copies outside the app remain until you delete them.
The Google Drive provisions below describe the optional feature in version 0.1.5. This privacy text does not confirm that this version is publicly available or approved by Google.
Google Drive backup
Google Drive backup is optional. You select a Google account and grant permission to save and retrieve backups in that account. The app requests access only to Drive files it creates or that you grant it access to, not your entire Drive. Automatic backups are off by default; you can separately enable daily or weekly backups. Execution depends on connectivity and Android’s background scheduling. Your Google account needs sufficient storage. Local backup and restore remain available without a Google account. A backup is not continuous synchronization between devices.
A backup contains locally stored schedules, shift types and recurring patterns, notes, important dates, pay and supplement settings, and relevant app and linked-calendar settings. It also includes technical file information such as the app version and creation time. Events from external device calendars are not included as calendar content. Purchase and licence entitlements, trial usage, the Google Drive account connection, access tokens, and device or folder permissions are excluded from the backup file. On another device, check linked calendars and required permissions again.
The app stores the email address and a Google account identifier locally, together with the selected backup frequency, enabled status and technical status information about the last checked copy or an error. This app uses Google access tokens temporarily in memory only and does not write them to its settings, backup files or logs. Google manages sign-in and authorization through its own services. Files and the necessary account and file information are exchanged directly with Google; Tempo Apps Studio does not operate its own backup server for this feature.
Traffic to Google uses HTTPS. TAS Shift Planner does not add a password or encryption to the backup file itself; someone with access to the file can read its contents. Share files carefully. The app reads an uploaded file back to check its contents and validates the file and its integrity before restoration. These checks are not encryption.
Backups are stored in the Drive folder ‘TAS Shift Planner Backups’. The app does not automatically delete older copies and does not apply a fixed retention period. When data has not changed, an existing checked copy may be reused. An interrupted upload may leave an incomplete file, which is not offered for restoration. You can delete files yourself in Google Drive and manage its trash. The app does not delete Drive files when you disconnect or uninstall it.
Disconnecting stops scheduled automatic backups and clears the local account connection and Drive backup status. It does not revoke the Google authorization previously granted. You can separately manage or revoke that authorization through your Google account. Existing local and Drive files remain in place.
Restoring requires explicit confirmation and replaces the relevant local app data with the selected backup’s contents. The app validates the file before replacement and temporarily preserves the original local data so that an interrupted or failed data replacement can be rolled back. The temporary recovery file is removed after a successful replacement or rollback. Restoring does not grant purchase entitlements or reset trial usage.
Google Play and licences
Google Play handles purchases, optional coffee contributions, updates and reviews under its own terms. The app receives product and purchase data to verify full access and restore purchases. It does not receive payment-card details. Verified purchase receipts and licence codes are stored locally. A local installation code binds a personal gift licence to that installation. Reviewer access uses a separate signed credential. Codes are checked locally.
For update checks, Google Play processes technical device and app information, such as the app version and installed components. If you submit a review, Google Play processes your rating and text; a public review is displayed on Google Play. You can delete reviews through your Google Play or Google Account. These Google services use encrypted connections and their own retention periods. See https://policies.google.com/privacy and https://play.google.com/about/play-terms/.
External links and contact
Website, social and contact buttons open an external app or browser. Those services process information under their own policies. If you email us, we receive the information you choose to include. Do not send private calendar data or backups unless necessary to address your question.
Retention and deletion
You can edit or delete items in the app and revoke permissions in Android settings. Your planning remains locally stored when the trial expires; no purchase or deletion happens automatically. Clearing app data or uninstalling the app can remove local data and installation-bound licences. Make a backup first when needed. Provider calendars, separately saved files and Google Play purchase records have their own retention and deletion controls. Tempo Apps Studio cannot erase local data on a device it cannot access.
