# Terms of Use > Terms of Use for Yuni, a period tracker for partners: plans, free days, cancelling and refunds, under the laws of England and Wales. Effective date: February 6, 2026 · Last updated: September 29, 2026 App: Yuni: Woman Cycles For Man · Contact: hello@yuniapp.co.uk ## 1) Acceptance of these Terms By downloading, installing, or using the App, you agree to these Terms. If you do not agree, do not use the App. ## 2) License and the Apple Standard EULA Your use of the App is also governed by Apple's **Licensed Application End User License Agreement (Standard EULA)**. If these Terms conflict with the Standard EULA, the Standard EULA controls where applicable. IAP Terms of Service: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ ## 3) What Yuni does Yuni is a relationship companion designed to help you navigate day-to-day communication and support by using cycle awareness and mood/phase-based guidance. The App may include features such as: - entering cycle dates or estimates and viewing an approximate "today" phase, - daily guidance, mood-matched tips, and what-to-say suggestions for each cycle phase, - streak tracking, challenges, and weekly recaps, - reminders and prompts, including optional Live Activities and Lock Screen widgets, - a "Share with Partner" feature that encodes cycle data into a shareable link — no data is sent to our servers, - importing cycle history from Apple Health and writing confirmed period dates back — with your permission and entirely on-device, - educational content and practical tips for communication, planning, and support. **Important:** any cycle predictions or phase estimates are inherently approximate and may be wrong. ## 4) Important: Your data and privacy (and third-party data) - **Your entries (e.g., dates, notes, reminders) are for your personal use.** - Depending on the App version and your settings, data may be stored **locally on your device** and/or via Apple-provided services (such as iCloud) that you control in iOS settings. - If you grant Apple Health (HealthKit) access, Yuni reads and writes health data **on your device only**. No HealthKit data is transmitted to our servers or any third party. You can revoke access at any time in iOS Settings → Health. - If the App offers optional features that require sending data over the internet (for example, syncing or restoring across devices), we will only do so as needed to provide that feature. If you enter information about **another person** (for example, a partner's cycle dates), you represent that you have a lawful basis to do so (including any consent required) and you will not use the App to harass, surveil, or control anyone. **Note:** Your device may back up app data depending on **your iOS/iCloud settings** (for example, iCloud Backup). That is managed by Apple and your settings — not by us. ## 5) Who can use the App You must be legally able to accept these Terms in your country. If you are under the age of digital consent where you live, a parent/guardian must consent and supervise your use. ## 6) Your responsibilities You agree to: - Use the App lawfully and not misuse it (e.g., no reverse engineering where prohibited by law, no interference with the App, no unlawful content use). - Use good judgment when acting on suggestions; you are responsible for your choices and how you communicate with others. - Keep your device secure and maintain backups if you want to protect your data (we generally can't recover your data if you delete the App, lose your device, or reset it). ## 7) Purchases and subscriptions Yuni Premium is sold in two places, and who you pay depends on where you bought it: - **In the iPhone app**, through Apple's **In-App Purchase (IAP)**. Apple processes the payment, and your billing relationship is with Apple. Availability, pricing, refunds, and subscription management follow Apple's rules and policies, including the Apple Standard EULA and Apple Media Services terms. - **On yuniapp.co.uk**, through Onelink, LLC, the seller of record for Yuni through Stripe Managed Payments. Onelink takes the payment, and your billing relationship for that plan is with Onelink. The terms for these plans are in [Subscriptions bought on yuniapp.co.uk](https://yuniapp.co.uk/terms/#subscriptions) below. - We check whether you have Yuni Premium using Apple-provided mechanisms for App Store purchases and Stripe's records for web purchases. ## Subscriptions bought on yuniapp.co.uk Web purchases are sold through Onelink, LLC, which acts as the seller of record for Yuni through Stripe Managed Payments. Onelink takes the payment, charges any sales tax or VAT, and sends your receipts. Yuni provides the service. Your statement shows the charge from Onelink as ONELINK* YUNIAPP.CO.UK (a plan change may read LINK.COM* YUNIAPP.CO.U). ### Plans The 12-month plan renews each year, the 1-week plan each week and the 1-month plan each month, at the price shown before you paid, until you cancel. Prices include tax. ### Free trial When the plans page offers it, the 12-month and 1-week plans start with a free trial of 3 days. The 1-month plan has no free trial. We email you when your trial starts and again about 24 hours before the first payment. If you cancel before the trial ends, you pay nothing. ### One plan covers you both While your Yuni accounts are paired, your plan gives your partner Yuni Premium too, on the web and in the iPhone app. If you unpair, or your plan ends, your partner's access ends with it unless they have their own plan. ### Cancelling Cancel any time from Settings in Yuni on the web, under Manage subscription, or with the Manage my subscription button in the emails we send about your free trial. You can also reply to any email from us, and we will cancel it for you. You keep Yuni Premium until the end of the period you paid for. Deleting your Yuni account cancels your web plan at the end of that period. ### Refunds If Yuni is not right for you, email hello@yuniapp.co.uk within 30 days of a payment and we will refund it in full. A refund also ends the plan at once, and Yuni Premium with it. In the EU and the UK you can also withdraw within 14 days of subscribing; if your plan has already started, you pay only for the days you used. ### Price changes If a price changes, we tell you by email at least 30 days before your next renewal, and you can cancel before it applies. ## 8) Health / medical disclaimer (very important) Yuni is provided for **informational and educational purposes only**. It is **not** medical advice, not a diagnostic tool, and not intended for contraception, fertility planning, or treatment decisions. If you or your partner have health concerns, seek advice from a qualified healthcare professional. Data imported from Apple Health (such as cycle history or symptoms) is used for informational guidance only and does not constitute a medical record or diagnosis. ## 9) Intellectual property The App, its design, text, UI, and any included assets are owned by us or licensed to us and protected by intellectual property laws. You may not copy, modify, distribute, sell, or lease any part of the App except as allowed by law or the Standard EULA. ## 10) Third-party services The App relies on the following third-party services: - **Apple** (App Store, iOS frameworks, iCloud if enabled) — governed by Apple's terms and policies. - **Adapty** (adapty.io) — subscription management and paywall functionality. Adapty receives limited purchase entitlement data to validate and manage your subscription. See Adapty's Privacy Policy. - **PostHog** (posthog.com): usage analytics hosted in the EU. See our Privacy Policy for details. - **Apple Health (HealthKit)** — on-device health data framework. HealthKit data stays on your device and is governed by Apple's privacy policies. Yuni does not transmit HealthKit data externally. ## 11) Disclaimers The App is provided **"as is"** and **"as available."** To the fullest extent permitted by law, we disclaim warranties of merchantability, fitness for a particular purpose, and non-infringement. We do not guarantee that the App will be uninterrupted, accurate, or error-free, or that any guidance will produce specific outcomes. ## 12) Limitation of liability To the maximum extent permitted by law: - We are not liable for indirect, incidental, special, consequential, or punitive damages. - We are not responsible for losses arising from reliance on estimates or guidance, relationship outcomes, or communications decisions you make. - We are not responsible for loss of data due to device failure, deletion, OS updates, user action, or third-party services (including Apple backup/sync features). Some jurisdictions do not allow certain limitations, so some of these may not apply to you. ## 13) Termination You may stop using the App at any time by deleting it. We may suspend or terminate access if you materially breach these Terms, to the extent permitted by law. ## 14) Changes to these Terms We may update these Terms from time to time. If changes are material, we will provide notice within the App or via the App Store listing where feasible. Continued use after an update means you accept the updated Terms. ## 15) Governing law These Terms are governed by the laws of **England & Wales**, without regard to conflict of laws principles. Courts located in **London** will have jurisdiction, except where consumer protection laws require otherwise. ## 16) Contact Questions about these Terms: hello@yuniapp.co.uk --- Canonical HTML: https://yuniapp.co.uk/terms/ Machine-readable index: https://yuniapp.co.uk/llms.txt Part of: https://yuniapp.co.uk/.well-known/ai-catalog.json
