Prex · A Pocket Shadow Theatre
The Lamp's Confession
What the light sees, what it keeps, and — mostly — what it refuses to take.
Confess it plainly. A shadow theatre should not cast one on your private life. This page is the lamp's confession: an honest accounting of everything Prex touches and, more importantly, everything it leaves alone. The short version is nothing leaves your device. The long version, told in nine vows, is just as reassuring.
I Do Not Ask Who You Are
Prex runs without an account. It never asks for your name, your email, your phone number, your birthday, your location, or a password to invent. There is no sign-up screen, no "verify your identity," and no profile that could be built about you. The curtain rises the moment you tap the icon, and the lamp is content to light a face it will never know.
I Do Not Phone Home
The theatre has no server to report to. Prex does not send your figures, your sunprints, your captions, or your preferences anywhere. There is no backend database wearing your name, no cloud vault, no usage ping that quietly lists what you traced last Tuesday. Where there is no transmission, there is nothing to intercept and nothing to breach.
I Do Not Watch You Wander
No analytics. No advertising networks. No third-party trackers, no fingerprinting, no "anonymous telemetry," no heat-maps of where your thumb taps. The lamp does not count how long you linger on a silhouette, and it certainly does not sell that number. The only tallies Prex keeps are the friendly ones you can see for yourself — figures forged, sunprints pressed, orb journeys taken — and those live on your device, not in a spreadsheet.
Your Photographs Stay Put
When you tap "choose a photo," your device offers you its library and hands Prex the single picture you selected — nothing more. Prex reads that image purely to guess its outline on the spot, using flood-fills and thresholds that run entirely on your own hardware. The chosen photo is not copied to a server, not added to any collection, and not used to train anything. The picture you didn't pick was never even offered.
- The photo library is opened only when you reach for the "photo shelf".
- Contours are computed on-device; the source image is not stored by the troupe.
- Declining the picker simply means no photo — nothing else changes.
What Lives Inside the Sandbox
The only things Prex remembers are written into small private files inside the app's own folder on your device: your cutout figures (as tidy lists of outline points and names), your pressed sunprints (a figure, an orb position, a backdrop, a caption), and your keeper preferences (favored backdrop, lamp warmth, dust toggle, and a few gentle tallies). These files are the theatre's prop room — sealed, local, and yours.
I Do Not Reach for the Camera Without Asking
Prex never opens your camera or reads your library on its own. The system only surfaces those requests when you deliberately start the "bring in an object" flow, and you may refuse at any time. Refusing is a complete answer — the rest of the theatre, including its seeded troupe of hand-drawn figures, keeps working without a single permission granted.
There Are No Third Parties in This House
Because there is nothing collected, there is nothing to sell, share, hand to an "analytics partner," disclose in a data marketplace, or forward under a subpoena about you specifically — the records simply do not exist on our side. No ad SDKs, no crash-reporting that ships your files, no social logins. The guest list is empty, and we intend to keep it that way.
Small Hands Welcome
Prex is a gentle toy for anyone who enjoys light and shadow, and because it collects nothing and shows no advertising, it is safe for curious children to play with. There is no chat, no contact with strangers, no purchases nagging at the corners of the stage, and no personal data to gather from a young keeper. Grown-ups can hand over the device with an easy mind.
You Hold the Eraser
Everything Prex knows is yours to unmake. Tear out a single print and it is gone. Dismiss a figure and its sunprints go with it. Delete the app and the entire troupe, album, and ledger vanish from the device at once — there is no copy on a server to request removal from, because no such copy was ever made. If we ever change the honest, local-only shape of this promise, you'll read about it here first, in these same plain words.
- Remove one memory: delete that figure or sunprint inside the app.
- Remove them all: uninstall Prex and the house forgets everything.
- Backups: your theatre travels only if you back up your own device.
