Privacy Policy

Effective July 10, 2026 · Covers Iron ID, Pocket Watch ID, Retro Flame ID, and Backstamp (together, “the apps”).

The short version:

What the apps do

Each app photographs a maker’s mark (on cast iron, a pocket watch, a lighter, or glassware) and tells you what it is. Recognition runs on your device first, using Apple’s built-in text recognition (OCR). For most scans, nothing leaves your phone.

Camera and photo library

The apps ask for camera access so you can photograph an item’s markings, and (if you use it) photo library access so you can pick an existing photo instead. Photos are used only to identify the item in them. The apps never scan your library in the background and never access photos you didn’t explicitly take or pick.

When a photo leaves your device

If the on-device read is low-confidence and AI identification is enabled, the app sends that one photo over an encrypted connection to our identification server, which passes it to our AI provider (Anthropic) to work out the maker and markings. The result comes back to your phone and that’s the end of it — the photo is processed to answer your scan, not to build a profile of you. Anthropic processes the image under its commercial API terms.

Text telemetry on missed scans

When a scan needs the AI fallback, the app also sends our server a small text-only record: what the on-device OCR read (for example, “WAGNERWARE”), how confident it was, and what the AI concluded. No image and no personal information is included. We review these records to improve each app’s identification catalog, so the next person’s scan works without the fallback.

Anonymous device identifier

Requests to our server include Apple’s identifierForVendor — a random ID that is not your name, phone number, or Apple ID and that we cannot link to you. We use it for one thing: a daily fair-use cap on AI identifications, so one device can’t run up our costs. It resets if you delete all of our apps.

What we don’t do

How long we keep things

Photos are processed to produce your identification and are not stored by us. The text-only miss records are kept only as long as they’re useful for improving the catalogs, then deleted. We keep no other data about you — your saved collection lives on your device, not our servers.

Purchases

All purchases (passes and subscriptions) are handled entirely by Apple through your Apple ID. We never see your payment details.

Children

The apps are not directed at children under 13, and we do not knowingly collect any personal information from anyone, children included.

Changes

If this policy changes in a way that matters, we’ll update this page and the effective date above.
