Drawings, progress and controls

The app stores saved drawing traces, best scores, progress and preferences locally. Doodle Drift does not upload your drawing traces or frame-by-frame steering and motion input. It does send the limited run summaries described below. Device backups may contain local app data under your Apple backup settings.

If you choose Tilt, the app uses motion-sensor input on your device to steer the pencil. That input is not sent to our purchase services. Hold Sides is available without motion permission.

Gameplay analytics, performance and errors

We use PostHog to understand whether the app is being used and how completed or interrupted runs perform. The app sends events when it opens, when a design is selected, and when a run starts or ends. A run summary can include the selected design, score, grade, completion or crash outcome, Line, Beat and Groove percentages, Ink Surge bonus, and whether the design is part of Full Sketchbook. It does not include your saved drawing trace, name, email address, contacts, advertising identifier, or raw motion-sensor readings.

PostHog also receives an automatically generated identifier and technical context such as app version, build number, device model and platform. Country and city may be derived from the connection IP when an event is received. The PostHog project is configured to discard the IP at ingestion rather than store it.

We use EAS Observe, provided by Expo, to measure startup performance and diagnose errors. It may process an anonymous identifier unique to an app installation; app, build, device and operating-system information; startup and rendering timings; slow or frozen frame counts during startup; battery, low-power and thermal state; network type and status; JavaScript error messages and stack traces; and supported native crash diagnostics. Doodle Drift does not add custom gameplay events to EAS Observe. Native crash reports are sent after a later launch because the app cannot transmit them while it is crashing.

These services are used for product analytics, performance monitoring, reliability and troubleshooting. Doodle Drift does not use this information for third-party advertising or to track you across other companies' apps or websites. Avoid including personal information when reporting a problem because error messages or support details can become part of diagnostic records.

Purchases and RevenueCat

Apple processes payments for Full Sketchbook. We do not receive your payment-card number. We use RevenueCat to validate purchases, unlock paid content, restore access and understand purchase activity.

RevenueCat processes purchase history and transaction information, entitlement status, an automatically generated app user identifier, and technical information needed to provide its service, such as app and SDK versions and store information. Purchase services may receive requests when the app checks access or loads the offer, even if you do not complete a purchase.

The app does not supply your name or email address as a RevenueCat customer attribute. An automatically generated identifier is not the same as collecting no data. Purchase information is used for app functionality and purchase analytics, not by this app to target advertising across other apps.

Read RevenueCat's privacy policy and Apple's privacy policy for their practices.

When you contact support

If you email us, we receive your email address and anything you choose to include, such as a bug description or screenshot. We use this information to respond, troubleshoot and resolve your request. Please don't send passwords, verification codes or payment-card details.

This website

These support and privacy pages are hosted through Cloudflare. Requests to the site involve ordinary connection information, such as your IP address, browser information and requested URL, which the hosting provider may process to deliver and protect the site. These pages do not add advertising scripts, analytics scripts or contact forms.

The site's server-side monitoring is configured to send request information to Honeycomb when enabled. This includes IP address, page path, browser and device information, referrer, request timing, response status, and approximate location and network information supplied by Cloudflare. This monitoring helps us understand site traffic and troubleshoot delivery; it is separate from the Doodle Drift app's local gameplay data.

See Cloudflare's privacy policy and Honeycomb's privacy policy. Following a link to another website is subject to that site's practices.

Retention, deletion and your choices

Local progress and settings remain until app data is removed. Deleting the app removes its local data, but does not erase Apple purchase records, information held by purchase providers, or copies in your backups. Reinstalling and restoring purchases does not guarantee recovery of your drawings.

Purchase, analytics, diagnostics and support information is retained as needed to provide and improve the app, troubleshoot reliability, resolve disputes, prevent fraud and meet legal obligations. EAS Observe states that metric data is retained for a minimum of 60 days. Other provider retention depends on the applicable service settings and policies. To request access, correction or deletion of information we hold, contact us below. Applicable privacy rights depend on your location. We may need information to locate your record and verify the request; some transaction records must be retained.

Children's privacy

We do not knowingly ask children under 13 to provide personal information. If you believe a child has sent us personal information, contact us so we can investigate and address it. In-app purchases are subject to Apple's account and parental controls.
