Privacy policy
How information is processed in the app and on this website, and how to manage your privacy choices.
Last updated:
Scope and developer
This policy covers mini Bubble Level (mini Su Terazisi, App Store ID 1111162128) and level.minilabs.app. Mert Tuzer is the app developer and handles support correspondence. Contact hello@mtuzer.com with privacy questions and data requests.
Motion sensors and reference values
The app uses motion-sensor information to calculate and display horizontal and vertical angles on your device. A reference angle is stored on the device for the app’s operation. In version 2.0, saving a reference sends the two calculated angle values (roll and pitch) to Firebase Analytics with the usage event “reference_angle_set”. Clearing a reference is also logged as an analytics event. It would therefore be inaccurate to say that no measurement-related information leaves the device.
Advertising and usage analytics
The app uses Google AdMob for banner advertisements and Google Analytics for Firebase to understand usage. AdMob may process IP addresses and an estimated general location, device/advertising identifiers, ad interactions and technical diagnostics. Firebase Analytics processes an app-instance identifier, device/app information, sessions and in-app usage events. These services support ad delivery and measurement, usage analysis and service operation. The information processed can depend on service settings and permissions.
Your privacy choices
Manage tracking permission in iOS or iPadOS under Settings > Privacy & Security > Tracking. When permission is denied, the app requests non-personalized ads; this does not stop all processing needed for ad delivery or all Firebase usage analytics. An operating-system tracking choice is not the same as deleting all analytics data.
This website
This is an information and help website. We do not add advertisements, visitor analytics or third-party font scripts. The reference slider runs only in your browser; it does not access motion sensors or send its values. Cloudflare hosts the site. To deliver pages and provide security, Cloudflare may process technical information such as IP addresses, browser information and request logs, and may use security cookies when necessary.
Support correspondence
If you send an email, your email address, message and any attachments you choose to provide are processed. We use these to respond to your request and follow up on the issue, and keep them for the time the request and necessary record needs remain. Avoid including unnecessary personal information. Send requests to delete your support correspondence to the same address.
Providers and retention
Advertising and analytics information is processed on Google’s infrastructure and may be processed outside the country where your device is located. Cloudflare processes technical website information. Provider retention, security and data choices follow the relevant service settings and policies. The provider disclosures are linked below. Contact our support address with questions about retention and deletion.
Questions, requests and changes
Send information, correction or deletion requests to hello@mtuzer.com. Requests are assessed against the information available to us and the options provided by the relevant service. The app has no user account, so there is no account-deletion button. If the app’s data practices or services change, this policy and its date will be updated.
