Privacy Policy
Last updated: October 28, 2026
This Privacy Policy explains how DRILL (“DRILL”, “we”, “us”) handles information in the DRILL iOS application (the “App”). DRILL does not require an account, ask for your name or email, sell personal information, or track you across other apps or websites.
Summary
- Your alarms, wake history, streaks, and settings are stored locally on your device.
- DRILL sends pseudonymous product-usage and reliability events to our analytics providers. This is on by default (in the EU, EEA, UK and Switzerland only if you agree) and can be turned off in Profile; when it is off, DRILL sends only anonymous counts that are not linked to you.
- Optional feedback includes the message you submit and basic app/device diagnostics.
- Subscriptions are processed by Apple and managed through RevenueCat.
- DRILL does not use advertising SDKs or App Tracking Transparency.
Information Stored on Your Device
DRILL stores alarms and their settings, wake-up events and statistics, onboarding preferences, and app settings locally. Widget summaries are shared only between DRILL and its widget through Apple's App Group storage. Uninstalling DRILL removes this local app data. If analytics is enabled, the random analytics identifier may remain in Apple's Keychain so an accidental reinstall does not create a duplicate user in our product measurements.
Product Analytics and Reliability
When detailed analytics is on, DRILL assigns a random installation identifier and sends events to Supabase and PostHog so we can understand onboarding completion, feature usage, alarm scheduling and completion, mission performance, paywall views, subscription entitlement status, and reliability problems. Detailed analytics is on by default. If your device region is in the European Union, the European Economic Area, the United Kingdom, or Switzerland, DRILL asks first and keeps it off unless you choose “Share usage data”. You can turn it off at any time in Profile → Share Usage Data; doing so deletes events still queued on your device. Events may include your onboarding selections (such as age range, gender, sleep and snooze habits, and wake-up times), app version and build, iOS version, device model, locale, time zone, Pro status, and alarm or mission configuration details. They do not include your alarm labels, name, email address, Apple ID, contacts, photos, or precise location, and we do not derive your location from your IP address.
When detailed analytics is off, DRILL still sends a small set of anonymous counts to PostHog: app launches, which onboarding screens are viewed, paywall views and closes, and purchase attempts and outcomes. Each count carries a new random value instead of your installation identifier, contains no session or RevenueCat identifier, and is not used to build a profile, so it cannot be linked to you or combined into a journey. It includes only the app version and build, the screen or paywall involved, and the product or outcome of a purchase attempt.
Detailed analytics events are pseudonymous but remain linked to the same random installation identifier so we can analyze a session and product journey. We may associate that identifier with RevenueCat's anonymous customer identifier to reconcile feature usage with subscription entitlement status. They are used only for product analytics, app functionality, support, and reliability—not advertising or cross-app tracking. Supabase and PostHog host this data on our behalf. See Supabase's privacy policy and PostHog's privacy policy.
Feedback
If you send feedback, we collect the category and message you provide along with the random installation identifier, app version/build, iOS version, device model, locale, time zone, Pro status, and the screen from which feedback was sent. Feedback is optional and is used to respond to issues and improve DRILL. Do not include sensitive personal information in a feedback message.
Notifications and System Alarms
DRILL uses local notifications and Apple's system alarm features to deliver alarms, mission reminders, mandatory re-rings, and optional wake checks. Disabling the relevant permission may prevent an alarm from working as intended.
Purchases and Subscriptions
Apple processes DRILL Pro purchases. RevenueCat manages subscription entitlement status using an anonymous customer identifier and purchase information supplied by Apple, such as product, purchase, renewal, and expiration status. DRILL does not receive your payment-card details or Apple ID. See RevenueCat's privacy policy.
How We Use and Share Information
We use information to operate subscriptions, measure onboarding and feature usage, diagnose alarm failures, improve the App, and process feedback. We share information only with service providers needed for these purposes: Apple, RevenueCat, Supabase, and PostHog. We do not sell information or use it for third-party advertising.
Retention and Deletion
On-device information remains until you uninstall the App. Analytics and feedback records are retained only as long as reasonably necessary for product analysis, support, security, and legal obligations. To request deletion of pseudonymous analytics or feedback data, send your DRILL Account ID (available in Profile) through the in-app feedback form. Apple, RevenueCat, Supabase, and PostHog retain information under their own policies and legal obligations.
Your Choices
- Manage alarm and notification permissions in iOS Settings.
- Turn detailed analytics on or off at any time in Profile → Share Usage Data (in the EU, EEA, UK and Switzerland you are also asked during onboarding).
- Manage or cancel your subscription in App Store subscription settings.
- Delete local data by uninstalling the App.
- Request deletion of server-side pseudonymous data through Profile → Send Feedback.
Children's Privacy
DRILL is not directed to children under 13, or the minimum age required in their region, and we do not knowingly collect personal information from them.
International Processing
Our service providers may process information in countries other than yours, subject to their safeguards and applicable law.
Changes
We may update this policy as DRILL changes. The date above identifies the latest version.
