Terms of Service

Last updated: 2026-11-06

These terms govern your download and use of the Bellows Android app ("the app"), developed by a single individual ("we", "us"). By downloading, installing, or using the app you agree to these terms. If you do not agree, do not download or use the app.

Your use of the app is also governed by our Privacy Policy.

The app

Bellows is a custom breathwork app for Android 7.0 and above, distributed through Google Play (package app.bellows.breathwork). The app works fully offline; the only network activity is with Google Play for purchases and paid content downloads, as described in the Privacy Policy. The app does not require an account — there is no sign-up, sign-in, or profile.

License to use

Subject to these terms, we grant you a personal, limited, non-exclusive, non-transferable, revocable license to install and use the app on Android devices you own or control, for personal, non-commercial purposes. We remain the owner of the app and its bundled content. This is a license, not a sale.

Purchases and Google Play Billing

The app is free to download and use. Optional purchases, all one-time and non-subscription:

Full Unlock — $5.99 USD, one-time. Removes the free-tier limits.
Tip jar — Coffee $1.99 USD, Lunch $4.99 USD, one-time each. Optional support; unlocks nothing.
Sound packs — $1.49 USD each, one-time. Additional ambient sounds via Google Play Asset Delivery.
Session packs — $2.49 USD each, one-time. Curated session bundles via Google Play Asset Delivery.

What you should know:

Purchases are non-consumable and permanent — they stay with the Google account that made them and work on every device signed in to that account. There is no subscription, no recurring charge, no trial, and no auto-renewal.
Prices, payment, taxes, receipts, and refunds are handled entirely by Google Play under the Google Play Terms of Service and Google Play's refund policies. We never see your payment details. If you need a refund, request it through Google Play.
The free tier allows 1 custom session, 3 set templates, and 9 pattern templates, with unlimited use of the bundled sounds and starter presets. We may adjust the free-tier limits in future app updates.

Your content

Sessions, sets, patterns, and favorites you create are yours. They are stored only on your device, in app-private storage, and we claim no ownership over them.
Sharing is peer-to-peer: every export — file, QR code, or deep link — is just text that encodes the session itself. Nothing is uploaded to any server. You are responsible for what you share and with whom you share it.
When you import a session someone shared with you, the app shows a preview dialog before anything plays. Treat imported content with the same caution you would any file or link you receive.

Health and safety

Bellows is a breathing-pattern timer. It is not a medical device and it is not medical advice, diagnosis, or treatment, and it is not a substitute for professional medical care.

Consult a physician before starting any breathing practice, especially if you are or may become pregnant, or if you have a cardiovascular, respiratory, or neurological condition (for example epilepsy, high blood pressure, or a panic or anxiety disorder).
Never use the app while driving or operating machinery. Practice in a safe position.
Intense breathing patterns — including the bundled Wim Hof method preset — can cause tingling or fainting. Practice seated or lying down.
Stop immediately and return to normal breathing if you feel lightheaded, dizzy, or unwell.

Acceptable use

You agree not to:

Circumvent the free-tier limits, purchase verification, or entitlement checks (for example by tampering with the app's local entitlement store to simulate a purchase).
Redistribute, resell, or extract paid sound or session pack content without purchasing it.
Reverse engineer the app, except to the extent that applicable law prohibits this restriction.
Use the app in any way that violates Google Play's terms or applicable law.

Google Play terms

The app is distributed through Google Play. Your use of Google Play, Google Play Billing, and Google Play Asset Delivery is governed by Google's terms — including the Google Play Terms of Service — which apply in addition to these terms. Nothing in these terms limits any right Google's terms give you.

Disclaimer of warranties

The app is provided "as is" and "as available," without warranties of any kind, whether express or implied. To the maximum extent permitted by law, we disclaim implied warranties of merchantability, fitness for a particular purpose, and non-infringement. The app is a fully offline product; we do not promise that it will be uninterrupted, error-free, or compatible with every device, and we may update, change, or stop distributing it at any time. Some jurisdictions do not allow the exclusion of certain implied warranties, in which case they apply to the extent required by law.

Limitation of liability

To the maximum extent permitted by law, we will not be liable for any indirect, incidental, special, consequential, or punitive damages, or for any loss of profits, revenue, data, or goodwill, arising out of or relating to the app. Our total liability for any claim arising out of or relating to the app will not exceed the greater of (a) the total amount you paid for purchases in the app in the twelve months before the event giving rise to the claim, or (b) USD $5.00. Nothing in these terms excludes liability that cannot be excluded by law, including mandatory consumer-protection rights under the laws of your country of residence.

Changes to the app and these terms

We may update the app through Google Play at any time. We may also update these terms from time to time; when we do, the "Last updated" date on this page changes and the revised terms take effect when published here. Continued use of the app after changes take effect means you accept the revised terms. If a change is material, we will also surface it in the app.

Termination

You may stop using the app at any time. Uninstalling removes the app's database, preferences, entitlement cache, and any downloaded asset packs from your device (see the Privacy Policy). We may terminate your license if you breach these terms, for example by tampering with purchase verification. Sections that by their nature should survive termination (purchases, disclaimers, liability, governing law) survive it.

Governing law and general

These terms are governed by the laws applicable at the developer's place of residence, without regard to conflict-of-law rules. This does not remove any mandatory protection the consumer law of your country of residence gives you. If any provision of these terms is found unenforceable, the rest remains in force. These terms, the Privacy Policy, and Google Play's terms are the entire agreement between you and us regarding the app.
