Blockhaus — Privacy Policy
Last updated: July 2026
Blockhaus is a home-building app: you draw rooms, build furniture from blocks, and share spaces with people you choose. This page is the whole story — there is no longer version with different answers.
What we collect
- Account — your name, email, and a user id, provided by Sign in with Apple or Google when you sign in. Nothing else about you.
- Your builds — the spaces, rooms, and furniture you create.
- Social actions — likes you give and guestbook notes you sign in public spaces (notes carry your display name).
What we don't collect
No location, no contacts, no advertising identifiers, no analytics brokers, no tracking across other apps or websites. There are no ads and your data is never sold.
Photos stay on your phone. Photos you convert to pixel art are processed entirely on your device — the photo itself is never uploaded. Only the coloured blocks are saved, and only if you choose to save them.
How your content is shared
- Private spaces and furniture are visible only to you and people you explicitly invite with a code.
- Public spaces and furniture are visible to all users in the Explore tab — that is what the Public switch means, and it is off by default.
Deleting your data
In the app, Profile → Delete account removes your account, your spaces, and your furniture permanently. Guestbook notes you've signed elsewhere can be deleted by you at any time.

WindUp — Privacy Policy
Effective August 2026
WindUp's watch tools run entirely on your device. The optional My Collection feature uses an account to sync and share your collection — this page explains exactly what that involves.
The watch tools collect nothing
Times, moon phases, sun calculations, power reserve, service logs — all computed and stored on your device. No analytics, no tracking, no advertising identifiers, no crash reporting. If you never sign in, WindUp sends nothing about you anywhere.
- Location is optional. If you grant it, it is used on-device to compute local sunrise and sunset — never stored beyond the last fix, never leaves your phone.
- Microphone is optional. The Beat Rate page can listen to a ticking watch to estimate its beat rate. Audio is analysed live on your phone and never recorded, stored, or sent anywhere.
- Time check. The Set Assistant can compare your phone's clock against Apple's time server (time.apple.com). That request carries no personal data — just the timestamps.
- Widgets read the same on-device data as the app. Nothing extra is collected.
If you use My Collection
Signing in creates an account so your collection can sync across devices and appear on your share page. This is what we store:
- Account — your name, email, and a user id, provided by Sign in with Apple or Google, plus the username you choose.
- Your collection — the watches you add: details, notes, prices, values, acquisition dates, and the photos you attach.
- App preferences — your widget layout and settings, synced so a new phone feels like the old one. These are private to your account.
- Paste a link to auto-fill — if you paste a product link, WindUp fetches that page directly from your phone, the way a browser would, to read the watch's name, reference and price. That website sees an ordinary page request from you; we never see the link.
Data is stored with Google Firebase (Firestore, Cloud Storage, Authentication) on servers in the United States. We use it only to run the feature — never for advertising, and we never sell it.
Sharing and privacy controls
- Your collection gets a public page at windup.web.app/u/<your username>. Anyone with the link can see what you choose to show.
- In-app toggles control what appears: photos, prices, values, wishlist, metrics — or flip Private Collection and the page shows nothing. Private mode is enforced on the server, not just hidden in the page.
- Prices and values you enter are visible on your page only if you leave those toggles on.
Deleting your data
- Deleting a watch in the app removes it and its photo from our servers.
- Delete Account (in the profile menu) erases everything — every watch, photo, preference, your username, and the account itself.
- You can also email us and we'll delete it for you.
Changes
If this policy changes, the update will be posted at this address with a new effective date.

NoteScreen — Privacy Policy
Effective August 2026
NoteScreen collects no data. None. Your notes live on your iPhone and nowhere else.
What NoteScreen collects
Nothing. NoteScreen has no analytics, no tracking, no advertising identifiers, no crash reporting, and no third-party SDKs. We never see anything you write.
How it works
- Fully on device — your notes are stored only on your iPhone (and in your personal iCloud device backup, which we cannot access).
- No network access. NoteScreen never connects to the internet and works identically in airplane mode.
- No account, no sign-in, no email — ever.
- Notifications are optional and local. If you schedule a note, NoteScreen uses a silent local notification to mark the transition — scheduled entirely by iOS on your device, sent nowhere.
- Lock Screen display uses Apple's ActivityKit on-device; your note text never leaves your phone.
Changes
If this policy ever changes, the update will be posted at this address with a new effective date. Since NoteScreen collects nothing, we do not expect it to change.

PushUpTrack — Privacy Policy
Effective August 2026
PushUpTrack collects no data. None. It counts your push-ups with the front camera, entirely on your iPhone.
What PushUpTrack collects
Nothing. PushUpTrack has no analytics, no tracking, no advertising identifiers, no crash reporting, and no third-party SDKs. We never see your workouts — or your face.
About the camera
- The TrueDepth front camera is used only to measure the distance between your face and the phone, which is how push-ups are counted.
- All processing happens on your device using Apple's ARKit. The camera feed is never displayed, never recorded, and never leaves your iPhone.
- No photos or videos are ever taken, stored, or transmitted — by us or anyone else.
How your workout history is stored
- Daily totals live on your iPhone and, if you're signed into iCloud, in your private iCloud database so your history follows you to a new phone. Only you can access it — we cannot.
- No account, no sign-in, no email — ever.
Changes
If this policy ever changes, the update will be posted at this address with a new effective date. Since PushUpTrack collects nothing, we do not expect it to change.
