Who to contact

For privacy questions about Rangr, contact its developer at support@dee.work. You can also visit the support page.

Information in the app

Rangr stores vehicle profile names, battery capacity, consumption and calculator settings locally on your device so you can use them again. It does not transmit those values to the developer or to an external service.

The app does not require registration, collect location data, access your contacts, or include advertising, analytics or tracking SDKs. Calculations take place on your device.

Managing your data

You can edit your saved values and rename or delete individual profiles in the app. At least one profile remains available. To remove Rangr’s local app data from your device, delete the app rather than offloading it.

Depending on your device settings, app data may be included in backups managed by Apple. Backup copies and restoration are controlled through your Apple and device settings; the developer cannot access those backups.

When you contact support

If you email the developer, the information you choose to send, such as your email address, message and attachments, is used to respond to your enquiry and resolve the issue. Please do not send sensitive information that is not needed for support.

Support correspondence is retained only as long as needed to handle the enquiry and related follow-up, or to meet applicable legal obligations. Contact the same address to ask about or request deletion of support correspondence.

This website

This website is hosted on GitHub Pages. It does not use developer-added analytics, advertising scripts or tracking cookies. Images and the demonstration video are served from this website.

GitHub logs visitors’ IP addresses for security purposes when serving GitHub Pages. GitHub handles hosting information under its own privacy statement. This hosting activity is separate from Rangr’s on-device app calculations.

Children’s privacy

Rangr does not collect personal information from children or other users through the app. If a child contacts support, please avoid including information beyond what is needed to answer the question.

Changes to this policy

This page will be updated if Rangr’s data practices change. The effective date above identifies the current policy.
