Terms of use

The agreement for using Oxigen, written to be read: what the app is and isn’t, how to use it safely, and how subscriptions work.

Last updated November 8, 2026

Agreement

These terms of use are an agreement between you and the publisher of Oxigen, shown as the developer on the app’s App Store page (“we”, “us”) about the Oxigen app and this website. By downloading or using Oxigen you agree to them and to our privacy policy. If you don’t agree, please don’t use Oxigen.

Who can use Oxigen

You must be 13 or older to use Oxigen. If you are under the age of majority where you live, use Oxigen with the permission of a parent or guardian, who agrees to these terms for you.

Wellness, not medical care

Oxigen is a wellness app, not a medical device. It does not diagnose, treat, cure, or prevent any medical condition. If you have a health condition or are pregnant, talk to your doctor before starting, and keep following your care plan.

Oxigen offers general wellness content: relaxation, managing everyday stress, winding down for sleep, focus and breathing practice. Evidence grades and studies are shown for information and describe research on feeling calmer, more alert or more focused, not on treating any condition. Heart-rate information from Apple Health or Health Connect is your data, not a diagnosis. Oxigen doesn’t replace advice from a doctor, and you should never delay seeking medical help because of something in the app.

Using Oxigen safely

  • Answer the health check honestly. It hides techniques that may not be right for you and keeps breath holds short.
  • Stop if you feel dizzy, faint or unwell: tap I feel unwell and breathe normally. If you have chest pain, severe breathlessness or feel faint, get medical help.
  • Intense techniques (fast breathing and breath holds after it) can make you faint without warning. Do them only sitting or lying down, and never in or near water, while driving, or standing.
  • Keep following your care plan, and don’t change or skip medication because of anything in Oxigen.

You use Oxigen at your own risk and are responsible for choosing a safe place and moment to practice.

Your license

We give you a personal, non-exclusive, non-transferable, revocable license to use Oxigen on devices you own or control, for your own non-commercial use, under these terms and the rules of the store you downloaded it from.

Subscriptions and trials

  • Oxigen is free to use. Oxigen Premium is an optional auto-renewing subscription, yearly or monthly, sold through the App Store or Google Play. Prices are shown in the app in your local currency before you buy (US prices: $44.99 per year or $7.99 per month).
  • Eligible new subscribers may get a 7-day free trial on the yearly plan. Payment is charged to your store account when you confirm the purchase, or when the free trial ends. Any unused part of a free trial ends when you buy a subscription.
  • The subscription renews automatically for the same period and price unless auto-renew is turned off at least 24 hours before the end of the trial or current period. You can manage or cancel it any time in your App Store or Google Play account settings; cancelling stops the next renewal, and Premium stays active until the end of the period you paid for.
  • Payments, refunds and billing are handled by Apple or Google under their terms; we can’t issue refunds ourselves. You can restore purchases on a new device from the paywall or You → Subscription.
  • If prices change, the store will tell you in advance as its rules require, and you can cancel before the new price applies.

Acceptable use

Don’t copy, modify, resell or redistribute Oxigen or its content; don’t reverse engineer it except where the law allows; don’t interfere with its security or operation; and don’t use it in breach of any law.

Ownership

Oxigen, including its design, text, pictures, sounds and software, belongs to us or our licensors and is protected by intellectual property laws. Fonts and icons are used under their open licenses. Data you create in the app stays yours and stays on your device.

Third-party services

Oxigen works with Apple Health, Health Connect, the App Store, Google Play and RevenueCat, and links to scientific publications. Those services have their own terms and privacy policies, and we aren’t responsible for them.

Disclaimers

To the extent the law allows, Oxigen is provided “as is” and “as available”, without warranties of any kind, express or implied, including fitness for a particular purpose, accuracy or uninterrupted availability. We don’t promise any particular result from using it.

Limitation of liability

To the extent the law allows, we aren’t liable for indirect, incidental, special or consequential damages, or for loss of data, arising from your use of Oxigen, and our total liability for any claim is limited to the amount you paid for Oxigen in the 12 months before the claim. Nothing in these terms limits liability for death or personal injury caused by negligence, for fraud, or any other liability that can’t be limited by law.

App Store terms

If you downloaded Oxigen from Apple’s App Store, these terms also include the following, and Apple’s Licensed Application End User License Agreement applies where these terms are silent:

  • These terms are between you and us, not Apple. We, not Apple, are solely responsible for Oxigen and its content.
  • Your license is limited to using Oxigen on Apple-branded products you own or control, as the App Store Usage Rules permit.
  • Apple has no obligation to provide maintenance or support for Oxigen. Support is ours: oxigen@thunder.red.
  • If Oxigen fails to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price, if any; to the maximum extent the law allows, Apple has no other warranty obligation.
  • We, not Apple, are responsible for addressing any claims relating to Oxigen, including product liability claims, claims that it fails to meet legal or regulatory requirements, and consumer protection, privacy or similar claims.
  • We, not Apple, are responsible for investigating, defending, settling and discharging any claim that Oxigen infringes a third party’s intellectual property rights.
  • You confirm you aren’t located in a country subject to a U.S. Government embargo or designated as a “terrorist supporting” country, and aren’t on any U.S. Government list of prohibited or restricted parties.
  • Apple and its subsidiaries are third-party beneficiaries of these terms and may enforce them against you.

Changes and ending

We may update Oxigen and these terms. If a change to the terms is significant, we’ll tell you in the app before it takes effect; continuing to use Oxigen after that means you accept the new terms. You can stop using Oxigen at any time by deleting it (and cancelling any subscription in your store account). We may suspend access if you seriously breach these terms.

Governing law

If you are a consumer, nothing in these terms takes away the protection of the mandatory laws of the country where you live, and you may bring claims in its courts. If any part of these terms can’t be enforced, the rest stays in effect.
