Lab reports on your iPhone

SERA does not require an account. You choose which PDFs, photos, camera scans or manually entered results to process. Text recognition and processing happen on your iPhone. SERA stores confirmed results, units, lab reference ranges and report details locally. It discards imported source copies and raw recognized text after import and leaves your original files intact.

The report database is excluded from device backups. SERA does not sync reports through iCloud or send them to its own servers. The app uses no ads, analytics trackers or advertising profiles. Reports stay on your device until you delete them in SERA or delete the app and its data.

Preferences and explanations

Your optional first name, any planned blood test date and your Apple Health export preference are stored in the app’s settings. You can remove your first name in Profile and a visible planned date in Overview.

SERA creates report summaries on your device. If Apple Intelligence is available, its on-device model can select explanations from SERA’s guide. SERA does not send lab results, report text or personal details to the model.

Apple Health and external sources

With your permission, SERA writes compatible individual measurements to Apple Health. You can turn off automatic export while reviewing an import. Manage write permissions and exported measurements in Apple Health. Deleting a report in SERA leaves previously exported measurements in Apple Health. See Apple’s Privacy Policy for its services.

If you open a source link, the destination website’s privacy policy applies. SERA does not attach lab results to these links.

If you email fohnemueller@gmail.com, we use your email address and message to respond and handle the issue. The mailbox uses Gmail. Please leave out health data. We keep correspondence only as long as needed to handle the request or meet legal obligations.
