Terms of Use

These Terms govern your use of Caelyn. By installing or using the app, you agree to them. If you don't agree, please don't use the app.

1. The agreement

These Terms of Use ("Terms") form a binding agreement between you and the publisher of Caelyn ("Caelyn," "we," "us," or "our"). They cover your use of the Caelyn iOS app and any subscription you purchase through it. They are read together with our Privacy Policy.

2. License to use Caelyn

Subject to these Terms, we grant you a personal, limited, non‑exclusive, non‑transferable, revocable license to download and use Caelyn on any Apple‑branded device that you own or control, in accordance with the Apple Media Services Terms (commonly called the "Standard EULA") that govern App Store purchases. The Standard EULA is available at apple.com/legal/internet-services/itunes/dev/stdeula.

You agree not to: (a) reverse engineer, decompile, or disassemble the app except where Apple's terms or applicable law expressly permit; (b) sublicense, resell, or rent the app; (c) remove any copyright or proprietary notices; or (d) use the app to violate any law.

3. Subscriptions (Caelyn Pro)

Caelyn offers optional Caelyn Pro access, available as an auto‑renewable subscription (monthly, with a seven day free trial, or yearly) or as a one‑time lifetime purchase, sold through Apple's In‑App Purchase system. Available tiers and prices are shown inside the app at the time of purchase and are processed by Apple, not by us.

• Auto‑renewal. Your subscription automatically renews at the end of each billing period (monthly or yearly, depending on the tier you chose) at the then‑current price, unless you cancel at least 24 hours before the end of the current period.
• Cancellation. You can cancel anytime in iOS Settings → [your name] → Subscriptions → Caelyn. Cancelling stops the next renewal; you keep Pro access until the end of the period you've already paid for.
• Price changes. If Apple notifies you of a price increase, the new price will only apply if you affirmatively consent in the manner Apple requires.
• Refunds. Refund requests are handled by Apple under their refund policy. You can request a refund through Apple at reportaproblem.apple.com. We do not directly process refunds.
• Family Sharing. Caelyn Pro can be shared with the members of your Apple Family Sharing group, subject to Apple's rules.
• Free trials and promotions. If we offer a free trial or introductory price, the relevant terms (length, conversion price, eligibility) are disclosed inside the app at the time of the offer. Unused portions of a free trial are forfeited if you purchase a subscription before the trial ends, where required by Apple.

4. Wellness, not medicine

Caelyn provides cycle predictions, pattern insights, and reminders for personal wellness purposes only. It is not a medical device, is not intended to be one, and has not been evaluated by the U.S. Food & Drug Administration or any equivalent regulator. Specifically:

• Caelyn must not be used as a method of contraception or to assess fertility for medical purposes.
• Caelyn's predictions are statistical estimates based on the data you log; they will sometimes be wrong.
• If you have any medical concern, see a qualified healthcare professional.

5. Your data, your responsibility

Caelyn stores your cycle data on your device only — it has no cloud sync. You are responsible for keeping your device secure (passcode, biometrics, OS updates), for any iCloud Backup settings you configure with Apple, and for exporting your data if you want a copy to keep elsewhere. Because we don't operate a server containing your cycle data, we cannot recover data lost to device loss, factory reset, or a "Delete all data" or duress‑wipe action.

6. Acceptable use

You agree not to use Caelyn to: (a) infringe anyone's intellectual property or privacy rights; (b) attempt to gain unauthorized access to any system; (c) interfere with the integrity of the app or its security features; or (d) use the app on behalf of someone else without their informed consent.

7. Intellectual property

Caelyn, including its name, logo, design, copy, app icon, illustrations, and source code, is owned by us and protected by copyright, trademark, and other laws. These Terms do not transfer any of those rights to you.

Anything you log inside the app — your cycle entries, notes, and exports — belongs to you. We claim no rights over your personal logs.

8. Disclaimers

The app is provided "as is" and "as available." To the maximum extent permitted by law, we disclaim all warranties, express or implied, including warranties of merchantability, fitness for a particular purpose, non‑infringement, accuracy, and uninterrupted operation. We do not warrant that predictions, insights, or reminders will be accurate, complete, or delivered on time.

9. Limitation of liability

To the maximum extent permitted by law, in no event will we be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for any loss of profits, revenue, data, goodwill, or other intangible losses, arising out of or relating to your use of (or inability to use) Caelyn, even if we have been advised of the possibility of such damages.

Where liability cannot be excluded as a matter of law, our total aggregate liability arising out of or relating to these Terms or the app is limited to the greater of (a) the amount you paid us through Apple for Caelyn in the twelve (12) months preceding the event giving rise to the claim, and (b) US$50.

Some jurisdictions do not allow some of these exclusions or limitations, so portions of this section may not apply to you.

10. Indemnification

You agree to defend, indemnify, and hold us harmless from any claim, loss, or expense (including reasonable legal fees) arising from your misuse of the app, your violation of these Terms, or your violation of any law or third‑party right.

11. Termination

You may stop using Caelyn at any time by deleting the app. We may suspend or terminate your access if you materially breach these Terms or if we are required to do so by law or by Apple. Sections that by their nature should survive termination will survive (including disclaimers, limitations of liability, indemnification, and governing law).

12. Apple‑specific terms

Because Caelyn is distributed through the Apple App Store, the following apply between you and Apple:

• These Terms are between you and us, not between you and Apple. Apple is not responsible for the app or its content.
• Apple has no obligation to furnish maintenance or support for the app.
• If the app fails to conform to any applicable warranty, you may notify Apple, and Apple may refund the purchase price you paid (if any). To the maximum extent permitted by law, Apple has no other warranty obligation, and any other claims, losses, liabilities, damages, costs, or expenses attributable to a warranty failure are our responsibility, not Apple's.
• Apple is not responsible for addressing claims you have relating to the app, including product liability, regulatory non‑compliance, or consumer‑protection claims.
• If a third party claims the app infringes their intellectual property rights, we, not Apple, are responsible for investigating, defending, settling, and discharging that claim.
• You represent that you are not located in a country subject to a U.S. Government embargo, or that has been designated as a "terrorist supporting" country, and you are not on any U.S. Government list of prohibited or restricted parties.
• Apple and its subsidiaries are third‑party beneficiaries of these Terms, and upon your acceptance, Apple has the right (and is deemed to have accepted the right) to enforce these Terms against you as a third‑party beneficiary.

13. Governing law and disputes

These Terms are governed by the laws of the State of California, U.S.A., without regard to its conflict of laws rules, except that mandatory consumer‑protection laws of your country of residence will continue to apply where they cannot be displaced by contract. The U.N. Convention on Contracts for the International Sale of Goods does not apply.

Any dispute arising out of or relating to these Terms or the app will be brought exclusively in the state or federal courts located in California, and you consent to the personal jurisdiction of those courts. Nothing in this section prevents either party from seeking injunctive or equitable relief in any court of competent jurisdiction.

14. Changes to these Terms

We may update these Terms from time to time. If we make a material change, we will update the "Effective" date at the top of this page and, where appropriate, surface a notice in the app. Continued use of Caelyn after an update means you accept the revised Terms.
