Rase Play

Privacy Policy

The Rase app, and this website · Last updated 15 September 2026

Neither the Rase app nor this website collects anything that says who you are. Nothing you do in either one reaches a server we operate, with one exception that is off unless you switch it on: the app's optional cloud reader for hand diagrams, described below.

The app does store things — your settings, your rubber, your saved hands — but on your own device, where we cannot reach them. What that does and does not mean is set out below.

This policy covers two things: the Rase app for iPhone and iPad, and the rasebridge.com website, which includes the version of the game you can play in a browser. They work differently, so each is described separately below.

The app: nothing is collected unless you turn on the cloud reader

The Rase app for iPhone and iPad runs on your device. There are no user accounts, no sign-in, no analytics, no crash reporting, no advertising, and no third-party services or SDKs embedded in it. It makes no network connections of any kind — with one exception, which is off until you switch it on yourself: the optional cloud reader in Diagrams, described below.

Unless you use that, nothing is transmitted, so there is nothing for us to collect, store, share, sell, or lose. We do not know who you are, that you installed the app, or how you use it.

The app: what is stored on your device

The app saves the following locally, in its own private storage, so that the app works the way you expect between sessions:

None of it is sent to a server we operate, apart from that key identifier, which goes with each photo you send to the cloud reader. We have no copy of the rest, no way to reach it, and no way to connect it to you. Deleting the app removes it from your device.

One honest qualification, because "stays on your device" is not the whole truth on a modern phone: if you use your device's own backup — iCloud Backup on iPhone and iPad — that backup may include the app's saved data, exactly as it includes other apps'. That copy sits in your Apple account, under Apple's terms rather than ours, and it is what lets your saved hands survive a new phone. It does not reach us and we cannot see it. If you would rather it were not backed up at all, you can switch the backup off, or exclude Rase from it, in your device's own settings.

The app: permissions

The app asks for one permission, and only when you use the feature that needs it: the camera, to photograph a bridge hand diagram in Diagrams. Choosing a screenshot or a photo instead uses the system's photo picker, which hands the app only the one picture you pick, so the app never has access to your photo library.

Unless you have turned on the cloud reader, the photo is read on your device by Apple's built-in text recognition, and it is not sent anywhere. So that you can check what was read, crop in closer and read it again, the app keeps the photo in its memory — never saved to storage — until you play the deal, start a new one or leave Diagrams for the home screen, and for no more than ten minutes in any case. After that it is discarded.

The app does not access your microphone, location, contacts, health data, or notifications.

The app: the cloud reader (off unless you turn it on)

Diagrams can also read a photo with Claude, an AI model made by Anthropic, which copes with more kinds of diagram than the reader built into your device. It is off by default; the app asks you before it is used for the first time, and you can switch it back to reading on your device in Diagrams whenever you like.

When it reads a photo, the app sends a reduced copy of it — redrawn, which leaves behind the location and other details a photo carries — to Rase's reader service, which runs on Cloudflare. The service passes it to Anthropic's API, Claude reads the cards, and the service sends them back to the app. Rase's service does not store the photo and does not log what is in it. Anthropic processes it as a provider to us, under its commercial terms, which govern how long it keeps what it is sent; its privacy policy is at anthropic.com.

So that only the Rase app can use the reader, your device proves it is running a genuine copy of the app with Apple's App Attest. That makes a key on your device, and the reader keeps the key's public half and a count of how many photos it has read for that key today, to apply a daily limit. The key identifies an installation of the app, not you: it is not linked to your name, your Apple ID, or any account, and we have no way to connect it to you.

This website

rasebridge.com sets no cookies and runs no analytics. There is no tracking pixel, no advertising network, no tag manager, and no third-party script of any kind on any page. The pages load nothing from any other company's servers, so no other company learns that you visited.

The site is hosted on Cloudflare Pages. Like every web host, Cloudflare receives and logs the ordinary technical details of each request — your IP address, the time, the page asked for, and your browser's user-agent string — in order to serve the page and to protect the site from attack and abuse. We do not build profiles from those logs, do not combine them with anything else, and have no way to connect them to you as a person. Cloudflare's handling of that data is governed by its own privacy policy.

Links to the App Store point at apple.com. Following one takes you to Apple, where Apple's privacy policy applies rather than this one.

Playing in a browser

The browser version is the same game as the app, served as an ordinary web page. Once the page has loaded, nothing further is fetched: the deal, the robots, and the double-dummy analysis are all computed on your own machine, and no card you play, and no score you record, is ever sent anywhere.

It saves the same things the app saves — your system and convention settings, the rubber in progress, completed hands, and Live Scorepad entries — using your browser's local storage, under the keys rb-settings, rb-rubber, rb-rubber-log, rb-live, rb-archive and rb-review. Two of those are worth naming for what they are: rb-rubber-log is the history of rubbers you have finished, and rb-review is not game data at all — it counts completed rubbers so that the app knows when it last offered you the chance to rate it, and does not ask again too soon. That storage belongs to your browser and stays on your device. It is not a cookie, it is never transmitted to us, and clearing your browser's site data deletes it. The same backup qualification applies: a device that backs itself up may include your browser's storage along with the rest.

Unlike the app, the browser version does need an internet connection to load the page in the first place, and will not open again without one.

Advertising

The app contains no advertising and never will. Nothing is sold inside it, and it has no in-app purchases or subscriptions.

This website currently carries no advertising either. If that changes, an advertising network would set cookies or similar identifiers, and this policy will be updated before any advert appears — saying which network, what it collects, and how to opt out. Visitors in the UK and the EU would be asked for consent first, and would be able to decline and carry on reading. The app would be unaffected in any case.

Children

Rase is suitable for all ages. This website collects no data from anyone, including children. The app collects none either unless the cloud reader is switched on, as described above — and even then nothing that says who is using it.

Changes to this policy

If this policy changes, the revised version will be posted on this page with an updated date. Where a change would mean actually collecting something that is not collected today — advertising cookies being the realistic example — it will be described here before it starts, not after.
