Privacy Policy

Last updated: 13 November 2026

Dry is a personal dry-day tracking app created by Tristan Thomas. This policy explains what information the app processes and how it is used.

Information you provide in the app

Dry stores the days you mark as Dry or Drank, your weekly target, your calendar settings, and your display theme.

How your data is used

Dry uses your data to:

• Show your calendar and weekly progress.
• Calculate stats such as streaks, averages, and monthly totals.
• Keep your widgets and Apple Watch up to date.
• Sync your tracking data across your own devices when iCloud is available.

Storage and syncing

Your tracking data is stored locally on your device. If iCloud is available and enabled for Dry, your data may also be stored in your private iCloud account so it can sync across your own devices.

If iCloud is not available, Dry falls back to local on-device storage.

Optional HealthPlus connection

If you choose to connect HealthPlus, Dry asks you to approve sharing the dates you marked Dry or Drank. It saves a copy of those dates and statuses in storage shared by the two apps on the same device. HealthPlus uses that copy to compare your tracking history with sleep data you have authorised it to read from Apple Health.

This connection does not send your Health data to Dry or upload the shared tracking history to a developer-operated server. You can disconnect in either app to stop sharing and clear the shared copy. Your original tracking history remains in Dry.

Sending feedback

If you choose Feedback in Settings, Dry sends your message, the app version and build, your iOS version and any photos or short videos you attach. It uses a protected installation identifier to authenticate requests and show your feedback history on that installation. Drafts stay on your device until you send them.

Feedback and attachments are stored privately with Cloudflare. The app removes location metadata from attachments. AI tools may help review your message, photos and selected video frames to investigate the issue and prepare improvements. Attachments expire after 90 days. Your message and its status can remain in your feedback history after the attachments expire. You can contact the address below to ask about or request deletion of feedback.

Accounts, analytics, and advertising

Dry does not require you to create an account. Dry does not include third-party analytics, advertising, or tracking SDKs.

Data sharing

Dry does not sell your personal data. Apple platform services, such as iCloud, process data as needed to provide storage, syncing, widgets and Apple Watch features. If you enable the HealthPlus connection, that app receives the local copy described above.

Deleting your data

You can remove local app data by deleting Dry from your device. iCloud-synced data can be managed through your Apple ID and iCloud storage settings.
