Privacy
This page describes what the software actually does. It was written by reading the code that does it, not by adapting somebody else's policy.
No accounts, no cookies, no third-party trackers
There is no sign-up and no password. This site sets no cookies at all. There is no Google Analytics, no advertising pixel, no social widget and no third-party script of any kind on any page — the fonts are served from this domain rather than from a font network, so no request for this site leaves it except the ones described below.
What stays in your browser
Your work is kept in your own browser's local storage, on your device:
- your saved walls — the "My walls" library, under
geowall-library-v1 - the wall you are working on, and the shared room settings it is drawn with
- a random visitor id, under
trimbid-analytics-visitor-v1, and a small buffer of unsent usage events
None of this is readable by us. Clearing your browser data deletes it — which is why a purchase is recoverable from your link and your email instead.
Usage events
The app records anonymous events so we can see where the tool is confusing. Seven event names exist and no others are accepted: opening the app, picking a style, measuring a wall, generating a plan, seeing the pay prompt, tapping unlock, and saving a wall.
An event carries a timestamp and a small set of properties — wall dimensions, the style, and counts such as how many pieces or obstructions a drawing came to. A rollup per visit records how long the visit lasted and how many plans, saves and unlocks it contained.
Alongside the parsed events, the raw batch your browser sent is stored verbatim as a second copy. It contains the same events and ids and nothing further; it is kept as insurance against a parsing mistake on our side.
What is not recorded, as a rule the collector enforces rather than a promise: no name, no email address, no postal address, no location, no free text you typed, and no contents of a saved wall. The visitor id is a random value — it is not derived from you or your device, and there is no fingerprinting of any kind.
The application does not record your IP address or your browser's user-agent string. Our web host keeps its own server access logs, as every web host does; those are the host's ordinary operational records and are not part of this system.
When you buy a plan
Payment is handled by Stripe on Stripe's own page. Card numbers never reach this site's server and are never stored by us. Stripe processes your payment under its own privacy policy.
Two things are stored on our server around a purchase.
When checkout starts, before payment completes, a copy of the wall design you are buying is uploaded and stored against the Stripe session — the wall's id and the design itself. This is what lets your link reopen the plan afterwards on any device.
When payment completes, Stripe tells our server, and a purchase record is written:
- your email address, as given to Stripe — the recovery path if you lose your link
- Stripe's session and payment references, the amount and currency, and the time of purchase
- the wall the purchase is for: its id, the width it was bought at, and — for support, never for access — the height, pattern and preset you were looking at
Your name is not stored. Stripe returns the cardholder name with every payment and this site used to keep it. It was never read by anything — a plan is delivered by email and by your link, and a name is part of neither — so as of 11 August 2026 it is not written at all.
Your unlock link is never stored. Only a one-way SHA-256 hash of it is kept, which is enough to recognise your link and not enough to reconstruct it.
Your email address is used to identify your purchase and to answer you. It is not added to a mailing list, and no marketing email is sent from this site — there is no mailing list to add it to.
How long it is kept
Purchase records are kept as the receipt for your purchase and as the means of restoring your plan if you lose it. Usage events are kept while they are useful. There is no automatic deletion schedule today, which is stated because it is true rather than left unsaid.
Asking for your data, or its deletion
Email plans@instantwallapp.com from the address you bought with, and you can have a copy of what is held about you, or have it deleted. Deleting a purchase record ends the link that reopens that plan — the plan you already downloaded is unaffected.
