Today, Just This — Last updated: March 20, 2026
We built Today, Just This to help people with chronic stiffness and pain move at their own pace, without judgment. We take your privacy as seriously as we take your comfort.
Arkalogy LLC ("we," "our," or "us") operates Today, Just This (the "App"), an adaptive daily movement companion. This Privacy Policy explains what information we collect, how we use it, and the choices you have.
By using the App, you agree to the collection and use of information as described in this policy. If you do not agree, please do not use the App.
When you create an account, we collect:
During onboarding and in your profile settings, you may optionally provide:
This information is stored locally on your device and, for premium subscribers, synced to our cloud servers. We never share your health information with advertisers, employers, or insurers.
As you use the App, we store the following to provide its core functionality:
This data is stored locally on your device. For premium subscribers, it is also synced to our cloud servers so you can access it across devices.
If you subscribe to premium features, the following is collected by Apple and shared with our subscription management provider (RevenueCat):
We do not receive or store your payment method details (credit card, billing address, etc.). All payment processing is handled by Apple.
We collect usage analytics to understand how the App is used and improve it. This includes screens visited, features used, and session counts. For authenticated users, analytics may be associated with a pseudonymous user identifier to help us understand usage patterns across sessions. We do not use analytics data for advertising or share it with advertisers.
For crash and error reporting, we collect device type, OS version, error context, and your account identifier to help us diagnose issues efficiently.
We use the following third-party services to operate the App. Each has its own privacy policy governing how it handles data:
| Service | Purpose | Data Shared |
|---|---|---|
| Supabase | Authentication, cloud database, file storage | Email, password (hashed), synced app data, session photos |
| RevenueCat | Subscription management | Pseudonymous app user ID, purchase receipts (via Apple) |
| Apple (App Store & APNs) | Payment processing, push notifications | Purchase transactions, device push token |
| Sentry | Crash and error reporting | Device type, OS version, error context, account identifier |
| PostHog | Product analytics | Pseudonymous user ID, usage events (screens, features, session counts) |
We do not sell, rent, or trade your personal information to any third party.
Your data is stored locally on your device in an encrypted database (SQLCipher, AES-256). The encryption key is stored in the iOS Keychain, meaning your data is unreadable without your device's secure hardware.
For premium subscribers, data is also stored on Supabase servers (hosted on AWS in the United States) with row-level security enforced at the database level. All data in transit is encrypted via HTTPS/TLS.
Sign-out vs. account deletion: Signing out preserves your local data so you can sign back in seamlessly. Deleting your account permanently removes your data from both your device and our servers.
In the unlikely event of a data breach affecting your personal information, we will notify affected users within 60 days via email and/or in-app notification.
Depending on your location, you may have the following rights:
To exercise any of these rights, contact us at privacy@arkalogy.com. You can also delete your account directly within the App.
If you are a California resident, you have the right to know what personal information we collect, request deletion, and not be discriminated against for exercising your privacy rights.
We do not sell or share personal information as defined under the CCPA/CPRA. Contact privacy@arkalogy.com to make a request.
If you are located outside the United States, your data is processed and stored in the United States. By using the App, you consent to the transfer of your information to the United States.
If you are in the EEA or UK, our legal basis for processing is: (a) your consent, (b) performance of a contract, and (c) our legitimate interests. You also have the right to restrict processing, object to processing, and withdraw consent at any time. You may lodge a complaint with your local data protection authority.
The App is not intended for children under 13. We do not knowingly collect personal information from children under 13. If you believe a child has provided us with personal data, please contact us and we will promptly delete it.
Today, Just This is a movement companion, not a medical device. It does not diagnose, treat, cure, or prevent any disease or condition. Always consult a qualified healthcare professional before starting any exercise program.
This website uses Google Analytics to collect anonymized visitor statistics. This is governed by Google's Privacy Policy.
We may update this Privacy Policy from time to time. We will notify you of material changes by posting the updated policy in the App or sending you a notification.
