Ebb (the “App”) is a menstrual-cycle and period-tracking app published by XTENZA TECH PRIVATE LIMITED (“we”, “us”, “our”). This page contains two documents: our Privacy Policy and our Terms of Use. You can contact us at any time at contact@xtenzatech.com.
Ebb is built to keep your health information private by design. Your cycle data is stored on your device. We do not operate servers that receive, store, or analyse your health data, and we do not have a copy of it. We cannot read your logs, your symptoms, your notes, or your predictions.
When you use Ebb, the following is created and stored locally on your iPhone (and, if you enable iCloud sync, in your own private iCloud — see Section 4):
This information is created by you, for you. It stays under your control.
Ebb has no user accounts and contacts no analytics or advertising services. We do not collect: your name, email, phone number, location, device identifiers for tracking, usage analytics, or any of your health data. There is no tracking across apps or websites. We do not sell or share personal information, and we do not use your data for advertising.
iCloud backup is off by default. Your data stays on your device unless you choose to turn it on — we ask once during setup, and you can change it any time in Settings → Data & Trust. If you turn on iCloud backup, Ebb stores your data in your own private iCloud database using Apple’s CloudKit, so it can sync across your Apple devices. This data lives in your personal iCloud account, governed by Apple’s Privacy Policy and your iCloud terms. We have no access to your iCloud data. Turning backup off stops future syncing; any data already copied to your iCloud may remain there until you delete it from your iCloud account.
If you grant permission, Ebb can read your past period/flow days from Apple Health to improve your first prediction, and can write the periods you log back to Apple Health so your data stays in sync. This exchange happens on your device, with your explicit permission. You control it in the iOS Health app and in Ebb’s settings, and you can revoke it at any time. We never receive your Apple Health data, and Ebb does not use Health data for advertising or share it with third parties. Data read from Apple Health is used only to provide the app’s features to you.
Ebb offers an optional premium subscription. All purchases are processed by Apple through the App Store. We never see or receive your payment-card details. Apple may share with us limited, non-identifying information about your subscription status (for example, whether an entitlement is active) so the app can unlock premium features. Apple’s handling of your purchase is governed by Apple’s terms and privacy policy.
We understand reproductive-health information is sensitive. Because Ebb does not transmit your health data off your device to us, we do not receive, store, share, or sell it, and we cannot be compelled to disclose data we do not hold. Information you choose to back up to your private iCloud, or to export and share yourself, is handled under the terms of those services and your own choices.
Your data is protected by your device’s security and, where applicable, iOS data protection and Apple’s iCloud encryption. Keep your device passcode and Apple ID secure. No method of storage is 100% secure, but because we never collect your data centrally, there is no central database of Ebb users’ health information to breach.
Ebb is not directed to children under 13 (or the minimum age required in your country), and we do not knowingly collect information from them. Because we collect no data centrally, the App’s health information remains on the user’s device under their control.
Depending on where you live (for example, under the EU/UK GDPR or the California CCPA/CPRA), you may have rights to access, correct, delete, or port your personal information, and to not be discriminated against for exercising them. Because Ebb keeps your data on your device, you can already exercise these directly: view and edit everything in-app, export it, and delete it. As we do not hold your data, there is typically nothing for us to retrieve or erase on our side. If you have questions, contact us at contact@xtenzatech.com.
Ebb processes data locally on your device wherever you are. If you enable iCloud sync, Apple may store your iCloud data in data centres in various regions per Apple’s policies.
We may update this Privacy Policy as the App evolves. We will revise the “Last updated” date above and, for material changes, provide notice in the App or on this page. Your continued use after an update means you accept the revised policy.

These Terms of Use (“Terms”) are a legal agreement between you and XTENZA TECH PRIVATE LIMITED governing your use of the Ebb application. By downloading or using Ebb, you agree to these Terms and to our Privacy Policy above. If you do not agree, do not use the App.
Ebb is a wellness and self-tracking tool, not a medical device or a healthcare provider. Its predictions are statistical estimates with an explicitly stated uncertainty, and they can be wrong. Ebb does not diagnose, treat, cure, or prevent any condition, and it is not a form of contraception or a fertility/birth-control method. Do not rely on Ebb to prevent or achieve pregnancy or to make medical decisions. Always consult a qualified healthcare professional with questions about your health. Your use of Ebb is at your own discretion and risk.
You must be at least 13 years old (or the minimum age of digital consent in your country) to use Ebb. By using the App you represent that you meet this requirement.
Subject to these Terms, we grant you a personal, limited, non-exclusive, non-transferable, revocable licence to use Ebb for your own non-commercial use on Apple devices you own or control, as permitted by the App Store Terms of Service. You may not copy, modify, reverse-engineer, resell, or redistribute the App except as allowed by law.
Ebb’s core predictions, logging, calendar, and backup are free. Certain features (such as deeper insights and the doctor-prep report) require a paid premium subscription. We may change which features are free or premium over time.
The App is licensed, not sold, and is also subject to Apple’s Licensed Application End User License Agreement (EULA). You agree to comply with applicable third-party terms when using the App. Apple is not responsible for the App or its content; Apple has no obligation to provide support or handle claims relating to the App; and Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you.
You agree not to misuse the App, interfere with its operation, attempt to circumvent purchase or security mechanisms, or use it in violation of any law.
The App, its design, and its content (excluding your own data) are owned by XTENZA TECH PRIVATE LIMITED and protected by intellectual-property laws. These Terms grant you no rights to our trademarks or branding.
The App 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 predictions will be accurate or that the App will be uninterrupted or error-free.
To the maximum extent permitted by law, XTENZA TECH PRIVATE LIMITED will not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of data, arising from your use of (or inability to use) the App, even if advised of the possibility. To the extent liability cannot be excluded, it is limited to the amount you paid us for the App in the 12 months before the claim. Some jurisdictions do not allow certain limitations, so some of the above may not apply to you.
You agree to indemnify and hold harmless XTENZA TECH PRIVATE LIMITED from claims arising out of your misuse of the App or violation of these Terms, to the extent permitted by law.
We may update the App and these Terms. Material changes will be reflected by the “Last updated” date and, where appropriate, in-app notice. Continued use after changes means you accept them.
These Terms apply while you use the App. You may stop using Ebb and delete it at any time. We may suspend or end the App or specific features, with or without notice, as permitted by law.
These Terms are governed by the laws of India, without regard to conflict-of-laws rules, and you agree to the exclusive jurisdiction of the courts of Coimbatore, Tamil Nadu, except where mandatory consumer-protection laws of your country of residence apply.
