Privacy Policy

Last updated: July 7, 2026

Dev Toolkit Mobile is a utility app for formatting, converting, generating, and inspecting developer data. This policy explains what information is processed by the app and by the advertising services used to support the free version of the app.

Information You Enter Into Tools

Text, JSON, JWTs, hashes, timestamps, UUIDs, cron expressions, diffs, and other content you enter into Dev Toolkit Mobile tools are processed locally on your device. We do not operate a server that receives, stores, or reviews this tool input.

Advertising and Tracking

Dev Toolkit Mobile uses Google Mobile Ads to display ads. The app may ask for permission to track you using Apple's App Tracking Transparency prompt. If you allow tracking, Google Mobile Ads may use your device's advertising identifier and related ad activity to provide personalized ads, measure ad performance, prevent fraud, and improve advertising services.

For App Store privacy disclosures, the data types that may be used for tracking are:

If you do not allow tracking, the app can still show ads, but they may be less personalized. You can change tracking permission later in iOS Settings.

Third-Party Services

Advertising data is processed by Google Mobile Ads. Google's handling of data is governed by Google's own privacy policies and service terms.

Data We Do Not Collect

Dev Toolkit Mobile does not require an account, and we do not collect your name, email address, contacts, photos, precise location, payment information, or user-generated tool input.

Children's Privacy

Dev Toolkit Mobile is not directed to children under 13. We do not knowingly collect personal information from children.

Changes to This Policy

We may update this policy when the app, advertising services, or legal requirements change. Updates will be posted on this page with a new effective date.
