Privacy Policy

Last updated: June 5, 2026

1. About This Policy

ClearStack Apps ("we", "us", "our") publishes a range of mobile applications. This page is the base privacy policy that applies to all of our apps. A small number of apps that handle especially sensitive data, or that work differently (cloud sync), have their own dedicated policy in addition to this one — see the list below.

Short version: The records, entries, and photos you create in a ClearStack app stay on your device — they are not uploaded to our servers. To keep our apps running we use Google's Firebase (anonymous crash reports and usage analytics) and, on the free tier of most apps, Google AdMob to show ads. Paying users see no ads.

2. What Stays On Your Device

The content you enter — projects, logs, journal entries, calculations, photos, and settings — is stored in a local database on your device. We do not operate accounts or servers that hold this content. A few apps offer an opt-in cloud backup; where they do, it is off by default and the app's own policy explains it. Our two business tools, SiteProof and TurnSnap, do sync data to the cloud as a core feature — see their individual policies for details.

3. What Is Sent To Google

By default these Google SDKs run inside our apps and send anonymised data to Google LLC:

  • Firebase Crashlytics — crash logs, stack traces, device model, OS version, app version. Used to find and fix bugs.
  • Firebase Analytics — anonymous app interactions, device model, OS, app version, and approximate location derived from IP. Used to understand how the app is used.
  • Google AdMob (free tier of most apps) — Advertising ID, device model, OS, approximate location, and ad-interaction events, used to serve ads. Paying users see no ads and AdMob is not initialised for them.

In the EU, UK, and EEA, our apps show a Google-certified consent form (UMP) on first launch where you choose whether ads are personalised. You can change that choice at any time in the app's settings.

4. Pricing & Purchases

Our apps are free to download. Depending on the app, an optional upgrade is available as a one-time purchase, a subscription, or both. Purchase status is verified by Google Play Billing and stored on your device. We never see or store your payment-card details.

5. What We Do Not Collect

  • The records, entries, photos, and notes you create (these stay on your device, unless an app's optional cloud backup or sync is enabled)
  • Your name, email address, phone number, or postal address
  • Precise location for advertising or profiling
  • Your contacts, calendar, messages, or files
  • Voice or audio recordings

6. Deleting Your Data

Uninstalling a ClearStack app removes its on-device data. To delete the anonymous Crashlytics, Analytics, and Advertising ID data already sent to Google, use Google's data-deletion process through your Google Account. Most of our apps have no user accounts, so there is no server-side account to delete; the exceptions (SiteProof, TurnSnap) describe account deletion in their own policies.

7. Your Rights (GDPR / UK GDPR / CCPA)

If you reside in the EU, UK, or California you have the right to access, delete, and object to the processing of your personal data, and to withdraw consent. For most of our apps we hold no personal data on our servers; Google holds anonymous device-level telemetry per its own policies. To exercise any right, email support@clearstackapps.com.
