These terms govern your use of the Phase iOS application ("Phase", "the App", "we", "us"). By installing or using Phase, you agree to these terms.

Note on the standard EULA: by default, Apple applies its Standard End-User License Agreement to any app distributed via the App Store. These additional Terms supplement Apple's EULA for the specific topics below. They do not replace it.

1. Not medical advice

Phase is a habit-recovery companion, not a medical device, not a substitute for professional medical or mental-health care, and not a treatment. Quitting smoking, alcohol, or other substances can have medical consequences (including withdrawal symptoms that may require supervision). Consult a qualified healthcare professional before making changes to your habits. If you experience a medical or mental-health emergency, contact your local emergency services or a crisis hotline immediately. Phase's "SOS" feature is a self-regulation tool, not a clinical intervention.

2. License

Subject to these terms and Apple's Standard EULA, you are granted a personal, non-exclusive, non-transferable, revocable license to use Phase on Apple devices you own or control.

You may not:

• Reverse-engineer, decompile, or disassemble the App except to the extent permitted by applicable law.
• Remove or alter any proprietary notices.
• Use Phase in any way that violates applicable law.
• Use Phase to harass, harm, or impersonate another person.

3. Phase Pro (in-app purchase)

• Phase Pro is a one-time, non-consumable in-app purchase ($29.99 USD or local equivalent at time of purchase).
• It is not a subscription. There is no recurring billing.
• The purchase is processed by Apple. All billing, refund, and payment-method questions are handled by Apple per their terms.
• If you reinstall Phase or move to a new device, use the "Restore Purchase" button in the paywall to recover your Pro entitlement using the same Apple ID.
• Family Sharing eligibility may be enabled. Check the App Store listing.

4. Your content and data

• All habit, craving, journal, and daily intention data you create in Phase belongs to you.
• Phase stores this data locally on your device. We do not have access to it.
• You can export your data in You tab → Data and delete it in You tab → Danger Zone at any time.

5. Optional analytics

You may opt into anonymous product-usage analytics via You tab → Privacy. The data we receive is described in the Privacy Policy. You can opt out at any time.

6. Acceptable use

Don't use Phase to:

• Build or train any machine-learning model based on Phase's outputs without our written permission.
• Scrape, redistribute, or resell any part of Phase.
• Attempt to circumvent the Pro entitlement check.

7. Third-party services

Phase integrates with:

• Apple HealthKit, StoreKit, and the App Store
• PostHog (analytics), only when you opt in
• Apple's on-device language model (Apple Intelligence), which writes craving responses, daily intentions, and weekly recaps on your device
• Featurebase, which hosts the public feature-request board at phase.featurebase.app

Use of these services is governed by their respective terms.

8. Disclaimer of warranties

Phase is provided "AS IS" and "AS AVAILABLE" without warranties of any kind, express or implied, including merchantability, fitness for a particular purpose, accuracy, or non-infringement. We do not warrant that Phase will be uninterrupted, error-free, or that streak / savings calculations are precise.

9. Limitation of liability

To the maximum extent permitted by law, in no event shall Jovain Chisholm, contributors, or affiliates be liable for any indirect, incidental, special, consequential, or punitive damages, including loss of data, loss of profits, or relapse-related damages, arising from your use of Phase. Aggregate liability for any direct damages shall not exceed the amount you paid for Phase Pro (if any) in the twelve months preceding the claim.

Some jurisdictions do not allow limitations on implied warranties or liability. In those, the limits above apply only to the extent permitted.

10. Termination

You may stop using Phase and uninstall at any time. We may suspend or terminate access to Phase or to Phase Pro features for material breach of these terms.

11. Changes

We may update these terms from time to time. The effective date at the top reflects the most recent revision. Material changes will be surfaced in the app's release notes. Continued use after a change indicates acceptance.

12. Governing law

These terms are governed by the laws of the jurisdiction where Jovain Chisholm is principally located, without regard to conflict-of-laws principles. Disputes will be resolved in the courts of that jurisdiction, except where applicable consumer-protection law grants you the right to bring a claim in your home jurisdiction.
