Effective date: November 1, 2026
RateProof is built to keep your data yours. Your studies stay on your device unless you share a report yourself. This policy describes the little the app does send, and how to turn it off.
Starting with version 1.2.1, RateProof sends anonymous usage data and crash reports, so we can see which parts of the app are used and fix what breaks. It is on by default, and you can turn it off at any time in the app: open About, then switch off Share anonymous usage data under Privacy.
Usage data is a count of things that happen in the app: the app being opened, a study being created or deleted, a cycle timer being started, how many cycle laps were recorded, a run tally being started, and a report being exported as a PDF or an Excel file. Each event also carries technical details: the app's version and build, the device model, iOS version, language and region, time zone, screen size, whether the device is on Wi-Fi or cellular, whether a foldable iPhone is open or closed, a random identifier created for this installation, and a session identifier. Anonymous here means it is not linked to your name, your email address, or any account, and the app has no accounts. The installation identifier only groups events from the same installation, and it is deleted when you switch sharing off.
Crash reports describe where in the app's own code a crash happened, with the same app and device details.
Usage data and crash reports never include study names, part numbers, supplier, site or engineer names, notes, cycle times, capacities, tallies, or anything else you type or measure. The app does not record your screen, your taps, or your location, and it does not track you across other apps or websites. Your IP address is discarded when the data arrives and is never used to work out your location.
When you switch it off, the app stops sending at once and deletes the usage data and crash reports it has not sent yet. Nothing more is sent until you switch it back on. The rest of the app works the same either way, offline included.
Capacity studies, cycle timings, production tallies, and notes you create in RateProof are stored on your device, in the app's private storage. The app never uploads them anywhere. Like other app data, they can be included in a backup of your device that you make through iCloud or a computer, which is handled by Apple and your own settings, not by RateProof. If you delete the app, its data is deleted from the device with it.
When you export a study as a PDF or Excel file, the file is created on your device and handed to the iOS share sheet. Where it goes from there, such as an email, a message, or a file location, is entirely your choice and happens outside the app.
RateProof requests no permissions. It does not access your camera, microphone, location, contacts, photos, or health data.
Usage data and crash reports are processed by PostHog, an analytics service, which stores them for us on servers in the United States. They are used only to understand and improve RateProof, never for advertising, and they are not sold or shared with anyone else. The app contains no advertising or tracking software.
This website is measured the same way, through PostHog, so we can see which pages bring people to the App Store. Each page sends an anonymous page view, with the page address, the address of the page that linked to it, and the screen and window size, and each click on an App Store button is counted with which button it was. On the calculator, the website also records which verdict was shown after you first changed the example study, such as by entering your own figures, and which verdict was on screen when you clicked an App Store button: a pass, a pass at risk, a fail, or none, never the figures you enter. The website sets no cookies. The only identifier is a random value your browser keeps for the current tab and discards when the tab closes. Your IP address is discarded when the data arrives. If your browser sends Global Privacy Control or Do Not Track, the website sends nothing at all. This page is never measured. Website data is used only to improve the website and is never used for advertising, sold, or shared with anyone else.
RateProof is a professional tool and does not knowingly collect personal information from anyone, including children.
If a future version of RateProof ever changes how data is handled, this policy will be updated before that version ships, and the change will be described in the app's release notes.
