Privacy Policy
Last updated: 2026-11-11
The short version. Bulbwick has no account, shows no ads and contains no analytics or tracking code. The rooms, saved looks and shopping notes you make stay on your iPhone. Only three things ever leave it: a small version check when the app starts, push-notification registration through OneSignal, and the messages you choose to send to support.
1. What stays on your iPhone, and what we do not collect
The lighting you set for each room, the room's size, ceiling height and wall colour, saved looks, shopping notes, your preferences (tactile clicks, area unit, seller card language) and the screen scale check are stored on the device only. They are never uploaded.
Bulbwick does not collect your name, contacts, location, camera or microphone input, the advertising identifier, browsing history or usage statistics, and it does not track you across apps or websites.
| Data category | Collected | Purpose | Kept | Third party | Your control |
|---|---|---|---|---|---|
| Rooms, saved looks, notes, preferences | No — stored on the device only | To show your rooms and notes again | Until you erase them | None | Settings → Erase rooms and notes, or delete the app |
| Device identifier (identifier for vendor, or the push subscription id) | Yes, at app start | Version check; delivering notifications | Server logs up to 30 days; OneSignal while you keep the app | Cloudflare (hosting), OneSignal | Delete the app; ask us to delete it |
| App version and bundle identifier | Yes, at app start | Version check | Server logs up to 30 days | Cloudflare | — |
| Push subscription and notification tags (first install, which screen opened) | Yes, through OneSignal | Delivering notifications | While you keep the app | OneSignal | Turn notifications off in Settings; ask us to delete |
| Analytics events | No | — | — | None | — |
| Crash diagnostics | Not by the app; Apple may share them if you enabled that in iOS | Fixing crashes | Per Apple's terms | Apple | iOS Settings → Privacy & Security → Analytics & Improvements |
| Advertising identifier (IDFA), attribution | No | — | — | None | — |
| Web cookies / local storage | Only if a service page is shown (see section 6) | Showing that page | Per the page | None | Delete the app |
| Help messages: text, attachments, optional email, optional device details | Only when you press Send | Answering you and fixing problems | In the support inbox up to 12 months | Cloudflare (delivery), our email provider | Ask us to delete them at any time |
2. The version check and device identifiers
Each time the app starts it sends one request to our server at https://api.bulbwick.info: the app's bundle identifier, its version number and a device identifier — the push subscription id if notifications are set up, otherwise Apple's identifier for vendor, which is unique to this app on this iPhone and resets when you delete the app. The answer tells the app whether a newer version is available. The identifier is not linked to your name or to any other app. If the server cannot be reached, the app simply opens as usual.
3. Push notifications
Bulbwick uses OneSignal to deliver occasional notifications. When the app starts, it registers with OneSignal, which stores a push subscription id, the identifier for vendor, the device model, iOS version, language, time zone and app version, plus two tags: that this is a first install, and which screen the app opened on. Notifications are only shown if you allow them; you can turn them off at any time in Bulbwick's settings or in iOS Settings → Notifications. OneSignal's own privacy policy applies to its processing.
4. Messages to support
Settings → Help & feedback offers ready answers and a form to write to us. Nothing is sent until you press Send. Then your message, any photos or files you attach, the reply email if you give one, and — only if you leave the switch on — device details (app version, build, iOS version, iPhone model and language) go to our support inbox at support@bulbwick.info. They are carried by Cloudflare, which stores nothing, and kept in the inbox to answer you, for at most 12 months. If our server cannot be reached, the app opens your Mail app with the same message instead.
5. Analytics, crash reporting, advertising
The app contains no analytics, crash-reporting or advertising software and does not ask for permission to track you. If you have chosen to share diagnostics with app developers in iOS, Apple may provide us with anonymous crash reports.
6. Web content
The privacy policy and support pages open inside the app in Safari's in-app browser. If our server ever needs to show a service page at start-up, it is displayed in an embedded browser, which may set cookies and local storage for that page. This website sets no cookies and loads no third-party scripts or fonts.
7. Children
Bulbwick is a general-audience tool rated 4+. It is not directed at children and we do not knowingly collect personal data from children.
8. Retention and deletion
Everything you create stays on your iPhone until you remove it: open Settings → Erase rooms and notes in the app, or delete the app. To have the version-check logs, the OneSignal record or your support messages deleted, write to support@bulbwick.info; include the reply email you used if you wrote to us. We act on requests within 30 days.
9. International transfers
Cloudflare, OneSignal and our email provider may process data in countries other than yours, including the United States, under their standard contractual safeguards.
10. Your rights
Depending on where you live, you may have the right to access, correct or delete your personal data and to object to its use. Write to us to use any of them; you may also complain to your local data protection authority.

12. Changes to this policy
This policy is effective from 2026-11-11. If the app starts using any service that changes what is described here, this page will be updated before that version is released and the date above will change.
