Ondaris Privacy Policy

Ondaris is published by SCOPT Inc. ("we", "us"). This policy explains what the Ondaris mobile application does with your information. It is short because the app does very little with it.

The short version

What we collect

Nothing that identifies you. We operate no servers of our own for Ondaris and hold no account for you, because there is no account to hold.

Ondaris does not collect, transmit or store:

• your name, email address, or any other contact detail — there is no account to create;
• your location;
• your advertising identifier, and nothing in Ondaris tracks you across other apps or websites;
• usage analytics, session recordings, crash reports or diagnostics;
• the calculations, projects, parameters or notes you enter.

The one exception is your purchase, and it is described under Purchases below.

What stays on your device

Ondaris stores the following locally, using your device's ordinary application storage:

• the projects, scenarios and shared parameters you create;
• your favourite calculators and recently used calculators;
• your settings, such as appearance and unit preferences;
• a record that you have purchased Ondaris Pro, so it stays unlocked.

This information never leaves your device unless you deliberately export it. It is removed when you delete the app, and you can clear it at any time from Settings, using "Delete all projects on this device".

When information leaves your device

One kind of request happens without you asking for it, and it is the first below. Everything else leaves the device only because you chose to send it.

• Purchases. When Ondaris starts, it asks RevenueCat, described under Purchases below, for the Pro price and whether Pro is unlocked, using the anonymous identifier described there. If you buy or restore Ondaris Pro, the store's receipt is also sent for verification. Nothing else about you is sent.
• Export. When you export a calculation as PDF, CSV, LaTeX, Python or MATLAB, the file is created on your device and handed to your operating system's share sheet. You choose what happens next — mail it, save it, or send it to another app. We never see it.
• Import. When you import a measured Touchstone (.s1p) file, it is read on your device and is not transmitted anywhere.
• Links. Opening a link from within Ondaris hands the address to your browser, which is then governed by that browser's own policies and by the policy of the site you visit.

Purchases

Ondaris Pro is a one-time in-app purchase. Payment is processed entirely by Apple or Google. We never see your payment details, your card, or your Apple or Google account.

To keep Pro unlocked on your devices, and to restore it if you reinstall or change device, we use RevenueCat (RevenueCat, Inc.) as a service provider. When you buy or restore Ondaris Pro, the app sends the store's purchase receipt to RevenueCat, which confirms whether a valid purchase exists. What is sent is the transaction information the store provides — the product bought and when — together with an anonymous identifier generated on your device and basic technical information about the app version and platform.

That identifier is anonymous and is not linked to you. Ondaris does not create an account, does not ask for your name or email, and does not set any identifier of its own, so the purchase record cannot be connected to your identity. No advertising identifier is used, and no data is used to track you across other apps or websites.

RevenueCat processes this information on our behalf under its own privacy policy, at https://www.revenuecat.com/privacy. If you never buy Ondaris Pro, no purchase information leaves your device: the only request the app makes is the check at start-up for the Pro price and whether Pro is unlocked, which carries the anonymous identifier and nothing else about you.

Children

Ondaris is a technical reference tool for engineering, aimed at students and professionals. It contains no advertising, no social features, and no user-generated content shared with others.

It does not knowingly collect personal information from anyone, of any age. The only information that ever leaves the device is the anonymous purchase check and purchase record described above, and neither identifies anybody — there is no account, no name, no email address and no advertising identifier.

Your rights

We hold no personal data about you. There is no account, and the purchase record described above is anonymous, so we could not connect it to you even if asked to. There is therefore nothing for us to disclose, correct, export or erase on request. The data the app holds is on your device and under your control, and the Settings screen removes it.

If you believe this is inaccurate, or if you have a question about it, please contact us using the details below and we will answer.

Changes to this policy

If Ondaris ever gains a feature that transmits information — for example an optional account or synchronisation — we will update this page before that feature ships, and the app will ask for your agreement before using it. The "last updated" date above will change.
