YOUR CONTROL
Privacy choices
Where to review permissions, manage information, export, and request help.
Apple Health access
On iPhone, open Settings → Health → Data Access & Devices → Trendline, or use the Health app’s Apps and Devices privacy controls. You can change access for each category at any time.
Health samples Trendline wrote
Trendline never writes to or deletes from Health automatically. Undo and confirmed deletion can remove only samples that Trendline wrote. Records from your scale, another app, or another source remain under your control in Apple Health.
App-owned data and iPhone backup
Use Trendline’s data-and-privacy controls to inspect or delete app-owned readings and clinic scans. This information is stored on your iPhone and may be included in your iPhone backup. Trendline does not send it to CloudKit or operate an iCloud sync service.
Export and sharing
Export and sharing are initiated by you through Apple’s system share interface. Review the selected information and destination before sending; the destination then controls the copy it receives.
Website and email updates
There is no Trendline website account, advertising profile, or cookie preference to manage. The interactive tools do not upload their inputs. Launch updates require email confirmation and every update provides an unsubscribe route. You may also email the privacy address below to request access to or deletion of your subscription information.
Request assistance
Email privacy@tracktrendline.app. Include enough information to understand your request, but do not email health records or sensitive measurements.
