Candle (“the app”) is a cozy, candlelit focus and study companion built by Adam Mierzwa (“we”, “us”). This policy explains what data the app handles. The short version: Candle has no accounts, no ads, and no analytics or tracking. Almost everything stays on your device.
This data is stored locally using Apple’s standard on-device storage. It never leaves your device except for the optional Study Rooms feature described below.
If you join or host a Study Room to focus alongside other people, the app connects to our server (hosted on Cloudflare at candle-rooms.adammierzwa.workers.dev) over a live connection and shares only:
Other people in the same room see your nickname and that you are present. This is live presence data that makes a shared session work; it is not stored as a long-term profile. We do not collect your real name, contacts, precise location, or any direct identity. If you never open a Study Room, the app makes no network calls of this kind.
The gentle one-line messages Candle shows are generated on your device using Apple’s on-device Foundation Models (Apple Intelligence), when your device supports it. These prompts and messages never leave your device. On other devices, Candle uses a small built-in set of pre-written lines.
Candle contains no advertising SDKs and no analytics SDKs. We do not track you across apps or websites, we do not sell data, and there are no third-party trackers. The app currently has no accounts and no in-app purchases.
Candle is not directed at children under 13 and does not knowingly collect data from them.
Your promises, Shelf, and nickname live on your device. To remove them, delete the app. Because we keep no long-term profile on our side, there is nothing for us to delete after you leave a Study Room. If you have any request or question about your data, email us and we will help.
If we make material changes, we will update the “Last updated” date above and, where appropriate, show a notice inside the app.
