Terms of Use

Last updated : 22 August 2026

1. Scope

These terms govern the use of the Barolog application, published by the party identified at the bottom of this page. Installing the app means accepting them. If you do not accept them, uninstall the app.

2. What the app does

Barolog records the atmospheric pressure measured by your phone’s barometer, fills the gaps with public weather data, and sets it against the episodes you log: migraines, joint pain, mood, fatigue. After several weeks of readings, it looks for a repeated coincidence between your episodes and pressure changes.

3. Medical disclaimer

Barolog describes coincidences in your data. It is not a diagnosis and does not replace medical advice.

Specifically:

• Correlation is not causation. The app may surface a statistical link where the real cause lies elsewhere.
• The app does not detect, prevent or treat any disease. It is not a medical device under Regulation (EU) 2017/745 and carries no CE marking as such.
• A missed, late or wrong alert must never be the basis of a health decision.
• Do not change, stop or start any treatment on the strength of what the app shows. Discuss it with a healthcare professional.
• For a severe, sudden or unusual symptom, call emergency services — 112 in the European Union.

The export document is material for a conversation with your doctor, not a medical report.

4. Free and Pro

The free version gives unlimited journal entries and correlation analysis on one symptom.

Barolog Pro adds analysis of all your symptoms and their comparison, alerts ahead of a pressure drop matching your profile, and the export intended for your doctor.

5. Purchases, subscription and cancellation

Barolog Pro is offered in two forms, at your choice:

• a yearly subscription, renewed automatically;
• a one-off purchase, permanent, with no renewal.

The applicable terms:

• Prices shown in the app are App Store prices, in your currency, including tax. They may change for the future; a price change on a running subscription is notified by Apple and requires your agreement in the cases its rules provide for.
• Payment is charged to your Apple account on confirmation of purchase.
• The subscription renews automatically for the same period unless cancelled at least 24 hours before the end of the current period. Renewal is charged within the 24 hours before the period ends.
• Cancel at any time under Settings > your name > Subscriptions on your device. Cancellation takes effect at the end of the period already paid for, which remains usable and is not refunded pro rata.
• “Restore purchases” returns access on your other devices and after a reinstall, provided you use the same Apple account.
• Refund requests are handled by Apple alone, through its support form. We have neither access to your billing nor the ability to refund on its behalf.

Right of withdrawal. By buying digital content supplied immediately, you request immediate performance and waive your fourteen-day right of withdrawal, in accordance with Article L221-28 of the French Consumer Code.

6. Your data

Your symptoms stay on your device. The detail is in the privacy policy, which forms part of these terms.

You are responsible for your own backups: uninstalling the app destroys the local database, and we hold no copy. No recovery is possible on our side.

7. Acceptable use

The app is provided for personal use. Decompiling it, circumventing the limits of the free version, or exploiting its results commercially or clinically without written agreement is prohibited.

8. Availability and changes

The app depends on third-party services — Apple’s store, the public weather service — whose downtime may temporarily degrade it. Features may change, and a paid feature that is withdrawn entitles you to a refund of the remaining pro rata of the current subscription.

9. Liability

The app is provided as is, with no warranty that its analyses are accurate, complete or suited to your situation. To the extent permitted by law, we are not liable for damage resulting from a health decision taken on the strength of the app, from the loss of local data, or from the unavailability of a third-party service.

Nothing here limits our liability for gross negligence, wilful misconduct, or personal injury.

10. Intellectual property

The app, its name, its visual identity and its code remain the property of the publisher. The content you enter remains yours.

11. Governing law and disputes

These terms are governed by French law. In case of a dispute, write to us first at the contact address at the bottom of this page. Failing agreement, you may use a consumer mediator free of charge, or the European online dispute resolution platform. French courts have jurisdiction, without prejudice to the consumer protection rules that let you bring proceedings where you live.

12. Changes

These terms may be updated; the applicable version is the one published on this page at the time you use the app. A substantial change is announced inside the app.
