Privacy

Last updated August 12, 2026

Lintel is built so there is almost nothing to have a policy about. There is no account, no sign-up, no analytics, no tracking, no advertising, and no server of ours. We cannot read your notes, we do not know who you are, and we collect no data about you. This page says what stays on your phone, what travels, and how to take any of it back.

What stays on your phone

Your name, the names you give the people in your rooms, any birthday or reading you offer to key the cards, your kept cards and verses, and your settings. All of it is written in the app's own container on your device. None of it is sent to us, because there is no us to send it to: the app has no backend.

What travels, and how

If you pair with another person, your notes cross between your two phones through Apple's iCloud, using the private sharing built into your own Apple account. Notes are written with CloudKit's encrypted fields, so their contents are sealed in transit and at rest. With Advanced Data Protection turned on in your iCloud settings, no one but the two of you can read them, not even Apple. What Apple necessarily holds, as the carrier, is the fact that two Apple accounts share a private area and the timestamps of writes. We hold nothing, because none of it passes through us.

Backups

Like most of what lives on an iPhone, the app's data rides along in your device's iCloud backup if you have backups turned on. That is your backup, in your account, governed by your iCloud settings.

Notifications

Lintel never sends you a notification. The app uses invisible background delivery so a note can be waiting when you open the room, and nothing ever lights your screen, plays a sound, or sets a badge.

Taking it back

Everything given can be given back, in the app, without asking anyone:

The keying. More → The keying → Remove the keying. Any birthday or pasted reading is deleted from the device, and the cards return to speaking plainly.

The pairing. More → Unpair. This phone stops sending and listening. Notes already on your phone stay readable to you; notes already delivered to the other person remain on their device, the way a handed-over letter does.

Everything. Delete the app. That removes the app's container from your device, and your standard iCloud settings govern anything in your own backup. If you were the one who created a pairing, you can also remove the shared data from your iCloud by unpairing first.

Children

A child in Lintel is a name and nothing else. The parenting room reads the parent, never the child: no birthday, no reading, no data of any kind is requested or held about a child beyond the name a parent chooses to write.
