Ondelle — Privacy Policy

Last updated: September 21, 2026

This Privacy Policy explains how SKJ Enterprises LLC ("we," "us," or "our"), based in Shawnee, Oklahoma, USA, handles information in connection with the Ondelle mobile application ("Ondelle" or the "App"). Please read it carefully. By using Ondelle, you agree to this Policy.

If you have questions, contact us at skjenterprisesllc2025@gmail.com.


The short version


1. Information you enter (health & cycle data)

Ondelle lets you log information such as period dates, symptoms, moods, basal body temperature, ovulation-test results, intimacy, pregnancy details, and personal notes. Cycle, fertile-window, and ovulation predictions are calculated from the information on your device.

This information is stored locally on your device. It is not transmitted to us, and we do not have access to it. If you create a manual export, you choose where to save or share that file. Treat exports as sensitive health information. Restoring an export happens on your device.

Because this includes sensitive reproductive-health information, we have intentionally designed Ondelle to keep this data on your device rather than on our servers.

2. Account information

The nickname and profile choices you enter to set up Ondelle are stored on your device to personalize your experience. They are not a cloud account; no email address or phone number is required to use the App. We do not transmit or store these profile details on our servers. If a future version introduces cloud accounts or syncing, we will update this Policy before that change.

3. Purchases

Ondelle Premium is available through monthly and annual subscriptions and a one-time lifetime purchase. Apple processes App Store billing. RevenueCat processes purchase and entitlement information needed to verify Premium access, such as a purchase identifier, product, and entitlement status. The purchase integration does not send your logged health entries to RevenueCat. We do not receive your payment-card details. Apple's and RevenueCat's handling of purchase information is governed by their respective privacy policies.

4. Diagnostic information

Apple may make crash or performance information available to developers according to your device and App Store sharing settings. We use any such information to investigate app issues, not to obtain your health entries.

5. How we use information

We use information available to us to operate and improve Ondelle, verify purchased features, and respond to support requests you send us. Ondelle does not display ads or use health entries for advertising.

6. How we share information

We do not sell your information. We share only as follows:

7. Data security & retention

Your health data is retained on your device until you delete it. We use reasonable measures appropriate to an on-device app. No method of storage is 100% secure, but keeping your data on your device — rather than on our servers — significantly reduces exposure.

8. Your choices and rights

9. Children

Ondelle is rated 16+ on the App Store. If you are under the age of majority where you live, please use Ondelle with the involvement of a parent or guardian. We do not knowingly collect personal information from children under 13. Because health data is stored on the device and not collected by us, contact us if you believe a child has provided information that you'd like addressed.

10. International users

Ondelle is operated from the United States. Your health entries remain on your device unless you choose to export them. Purchase and entitlement information is handled by Apple and RevenueCat under their respective policies and infrastructure, which may involve processing outside your country.

11. Changes to this Policy

We may update this Policy from time to time. We will post the updated version with a new "Last updated" date, and significant changes will be reflected in the App or on our website.
