Terms of Use

The short version: Orsa is a tracker you own a licence to, not a doctor, and Apple handles the money.

Accepting these terms

These terms are the agreement between you and PXL Security LTD, Sofia, Bulgaria ("we", "us"), which publishes Orsa. By downloading or using the app you accept them. If you do not accept them, please do not use Orsa.

Your licence

We give you a personal, non-exclusive, non-transferable, revocable licence to use Orsa on Apple devices you own or control, for your own health tracking. That licence is what you get; every other right in the app stays with us.

You may not copy, sell, rent, sub-licence or redistribute the app, reverse engineer or decompile it, remove its notices, or get around any technical restriction in it — except where the law allows you to regardless of what this agreement says.

Purchases and subscriptions

Orsa is free to download and free to use for its core stand test, symptom log and export. Orsa Pro is optional and comes two ways: a one-time lifetime purchase of $24.99, or a $9.99 per year subscription with a seven-day free trial.

Both are sold through Apple's App Store. Apple takes the payment, holds your payment details and issues the receipt; we never see your card.

The yearly subscription renews automatically at the then-current price unless you cancel it at least 24 hours before the end of the current period, and your Apple Account is charged within 24 hours of the period ending. A free trial converts to a paid year on the same basis. You can see, manage and cancel a subscription at any time in your Apple ID settings on your device; cancelling stops the next renewal but does not shorten a period you have already paid for. The lifetime purchase never renews and never bills you again.

Refunds are handled by Apple under Apple's own terms, not by us. We cannot grant or refuse a refund on Apple's behalf, though you are welcome to write to us and we will help where we can.

Not medical advice, not a medical device

Orsa is a wellness and self-tracking app. It is not a medical device. It does not diagnose, treat, cure or prevent POTS, dysautonomia or any other condition, and nothing it shows you is medical advice.

An at-home stand test is not a tilt-table test and cannot confirm or rule out a diagnosis. Reference lines, charts and summaries are there to help you describe your own pattern to a clinician — not to replace one. Do not start, stop or change any treatment on the basis of what the app shows, and do not delay seeking care because of it. If you feel unwell or lose consciousness, contact a healthcare professional or your local emergency number.

Acceptable use

Use Orsa lawfully and for yourself. Do not use it to give anyone else a diagnosis or clinical instruction, do not present its exports as a clinical report, and do not interfere with the app, with Apple Health or with Apple's services. Test safely: never do a stand test alone if you are prone to fainting, and sit or lie down the moment you feel faint.

Your data and your backups

Everything you record lives on your own phone — see the Privacy Policy. Because we hold no copy, keeping backups is your responsibility, through your own device backup or the app's export. Deleting the app deletes its data, and we cannot recover it for you.

Availability

We may change, add to, or discontinue Orsa or any of its features, and we may stop supporting older versions of iOS. We will try to give reasonable notice where a change matters, but we do not promise that the app will always be available or uninterrupted. Features that depend on Apple Health depend on Apple, not on us.

Disclaimer of warranties

Orsa is provided "as is" and "as available". To the fullest extent the law allows, we make no warranties about it, express or implied, including merchantability, fitness for a particular purpose, accuracy, or error-free operation. Heart-rate readings, timings and charts can be incomplete or wrong. Nothing here removes rights you have as a consumer under Bulgarian or EU law that cannot be excluded by agreement.

Limitation of liability

To the fullest extent the law allows, we are not liable for indirect, incidental, special or consequential losses, for lost records, or for any health outcome or decision made or not made on the basis of the app. Where liability cannot be excluded, it is limited to the amount you paid for Orsa in the twelve months before the claim.

Changes to these terms

We may update these terms as the app changes. The current version always lives at this address with the date it took effect, and continuing to use Orsa after a change means you accept it.

Governing law

These terms are governed by the laws of Bulgaria, and disputes will be dealt with by the competent Bulgarian courts. If you are a consumer resident elsewhere in the EU, you keep the protection of the mandatory laws of your own country.
