Do Hedah or Perith require an account?
No. Hedah and Perith are designed so core app use does not require a Ylemos account.
Where is my app data stored?
Core data is stored locally. When household sharing is enabled, Hedah uses Apple iCloud and CloudKit to keep invited family iPhones and a family iPad in sync, including devices using different Apple Accounts. Pro AI features send the request and limited household context needed to generate a response.
How do I request support or report a problem?
Email service@ylemospure.com with the app name, your device model, iOS version, and a short description of the issue.
Can I delete my information?
Yes. You can delete app entries inside the app where available, or remove the app from your device to delete locally stored app data.
Is Perith medical advice?
No. Perith is for personal tracking and educational reflection. It does not diagnose, treat, or replace advice from a qualified clinician.
This Privacy Policy explains how Ylemos Inc handles information for Hedah and Perith, our mobile applications available through the App Store.
1. Apps Covered
This policy applies to Hedah, a family dashboard app, and Perith, a perimenopause companion app. In this policy, we refer to both products as the apps.
Ylemos Inc is a Wyoming, USA company and a subsidiary of Antigravity AI. You can contact us at service@ylemospure.com.
2. No Account Required
The apps do not require you to create a Ylemos account. We do not ask you to sign in to Ylemos servers to use core app features.
If you contact us for support, we will receive the email address and information you choose to include in your message.
3. Information You Enter
Hedah may let you enter household plans, routines, reminders, notes, or related family organization information.
Hedah imports calendar events only from the calendar sources you explicitly enable. You can assign a source to a family member, hide it from the family iPad, or show its events only as Busy.
Hedah stores copies only of photos you explicitly select and send to the family screen. It does not scan your photo library, automatically import recent photos, or write copies back to Apple Photos.
Perith may let you enter symptom notes, cycle information, mood, sleep, energy, journal entries, and related personal health context.
Perith entries are intended to remain on your device. Hedah stores core entries locally and may process selected calendar copies, explicitly sent photo copies, and household entries through Apple iCloud and CloudKit when household sync or sharing is enabled.
A household owner can invite other people through Apple's CloudKit sharing. Invited participants use their own Apple Accounts and can access the shared household after accepting the invitation. The owner can stop sharing or remove participants using the controls provided by Apple and Hedah. A pairing QR code is an optional shortcut for an iPad using the owner's iCloud account; it is not required for invited family members.
When you choose a Hedah Pro AI feature, your prompt and limited household context relevant to that request, such as member names, meal plans, or grocery items, are sent to Ylemos's service and its AI provider to generate the response.
4. Local Storage, iCloud, and AI Processing
The apps use local storage by default. Apple system features, including iCloud, device backup, PhotosPicker, Share Sheet, or app transfer tools, may process data when you enable or use them. Apple's terms and privacy policies govern those services.
Hedah Pro AI requests are sent over an encrypted connection to a Ylemos-operated backend hosted by a service provider and then to OpenAI to generate a response. Do not include information that is not needed for your request.
Ylemos does not use household content or AI prompts for advertising. Service providers may process request data and technical logs as needed to deliver, secure, and troubleshoot the service.
Ylemos does not maintain an AI conversation-history database or intentionally retain AI prompt and response content after returning a response. Our backend logs the request time, method, and path for operations, but not the request body. OpenAI may retain API abuse-monitoring logs, which can include prompts and responses, for up to 30 days. OpenAI states that API inputs and outputs are not used to train its models by default unless the customer opts in; Ylemos has not opted in.
5. No Third-Party Trackers
Ylemos Inc does not include third-party advertising trackers in Hedah or Perith. We do not sell your personal information. We do not use your app entries for behavioral advertising.
We also do not embed third-party analytics SDKs for cross-app tracking.
6. Diagnostics and App Store Data
Apple may provide developers with aggregated App Store information, crash reports, performance metrics, or diagnostics depending on your device settings and Apple programs. This information is provided by Apple and is generally aggregated or diagnostic in nature.
We use this information only to understand app reliability, fix bugs, and improve the apps.
7. Support Communications
If you email service@ylemospure.com, we collect the contents of your email, your email address, and any attachments or details you choose to send. We use that information to respond to your request, troubleshoot issues, and keep a record of support history.
Please do not email sensitive health information unless it is necessary for your support request.
8. Health and Family Information
Perith may involve personal health-related notes because you choose to enter them. Hedah may involve family or household information. We limit processing to the storage, sync, sharing, support, and AI functions described in this policy.
Perith is not a medical device and does not provide diagnosis, treatment, or medical advice.
9. Children and Families
Hedah may be used by families to organize household routines. The app does not require children to create accounts with Ylemos. Parents or guardians are responsible for deciding what information they enter and which people they invite into a shared household.
10. Data Deletion
You can delete information inside the apps where deletion controls are provided. Removing an app deletes its local data, but copies in iCloud or device backups may remain subject to your Apple settings and Apple's retention practices.
You can stop Hedah AI processing at any time by not using Pro AI features. You can remove Hedah data from iCloud through your Apple ID iCloud storage settings and can cancel a Pro subscription in your App Store subscription settings. Because Ylemos does not maintain user accounts or an AI conversation-history database, there is no separate Ylemos account record to delete.
If you have contacted support and want your support email deleted from our records, email service@ylemospure.com with your request.
11. Data Sharing
We do not sell your personal information or share app entries with advertisers. Depending on features you choose, data may be processed by Apple for iCloud and CloudKit household sharing, by household participants you invite, by our hosting provider for Hedah's AI service, and by OpenAI to generate AI responses. We may also disclose information if required by law, to protect rights and security, or to respond to support requests using business service providers.
12. Security
We use a privacy-first product design and rely on iOS security features for locally stored app data. No method of storage or transmission is perfectly secure, so you should protect your device with a passcode, biometric lock, and current software updates.
13. International Users
Ylemos Inc is based in the United States. If you contact us, your email may be processed in the United States or in other locations where our email and business service providers operate.
14. Changes to This Policy
We may update this Privacy Policy when our apps, legal requirements, or business practices change. The updated version will be posted on this page with a new last updated date.
