Is there a seizure diary that keeps data on my phone?

Short answer: yes. Présence keeps your entries on your iPhone, with no Présence account to create, no Présence servers, no Présence cloud sync, and no ads, analytics, or tracking (privacy policy). That isn’t the same as zero risk: your phone, the files you export, and your Apple settings still matter.

Many families would rather not hand health notes about their child to another company. Présence doesn’t ask you to sign up, and your diary isn’t stored on servers of ours.

What stays on the phone

• Episodes, checklists, notes, and history
• The profile you choose to fill in (name, age, medications, photo, height, weight)
• Weather snapshots after they’re saved

What can touch the network or leave the phone

• Weather: logging an episode asks Apple Weather for a snapshot at your approximate location. No diary content is sent with that request.
• Siri: your voice is processed by Apple under Apple’s terms. Présence only receives the command.
• Apple Health, if you turn it on: off by default. Présence doesn’t send Health data to us. How Apple Health itself stores or syncs data is governed by Apple and your device settings.
• Exports: a PDF report or CSV only leaves the phone when you choose to share it, and then it goes wherever you send it.
• Purchases, after launch: Apple handles payment. We never see card details.

Backups and exports

Présence has no cloud sync of its own, so the support page suggests exporting a report or CSV now and then if you want your own copy. Deleting the app deletes the data, and we can’t recover it because we never had it. Whether your phone’s own system backup includes app data depends on your device settings, so don’t count on it without checking.

A report or CSV contains sensitive health information. Share it only with people who need it, through a channel you trust, and remember that once sent, it’s out of the app’s hands.

The full details are in the privacy policy.

Présence is a personal wellness diary, not for emergencies. It doesn’t diagnose, treat, monitor, or alert. This guide isn’t first aid. Follow your child’s individual seizure action plan. If an episode is different from their usual pattern or you are unsure what to do, contact their care team; get emergency help for immediate danger such as trouble breathing or serious injury.
