OMNISC Cookie & Technology Policy

Effective Date: 2026-04-01

This Cookie & Technology Policy explains what cookies and similar client-side storage technologies Omnisc uses, why we use them, and how you can manage them.

This Policy should be read together with the Terms of Use and Privacy Policy.

1. What Are Cookies and Similar Technologies

Cookies are small text files placed on your device by a website. Similar technologies include localStorage, sessionStorage, and other browser-based storage mechanisms that allow websites to store data locally on your device.

Different technologies serve different purposes. Some are strictly necessary for a service to function. Others may be used for analytics, advertising, or personalization.

2. What We Use

At MVP launch, Omnisc does not use traditional browser cookies.

Instead, we use localStorage, a browser-based storage mechanism, for the following strictly necessary purposes:

A. Authentication and Session Management

When you sign in to Omnisc, we store the following data in your browser's localStorage to maintain your authenticated session:

Access token — a short-lived authentication credential used to verify your identity on each request. Expires after 1 hour; automatically refreshed while your session is active.

Refresh token — used to obtain a new access token without requiring you to sign in again. Expires after 30 days or when you sign out.

User profile — basic account information (email, subscription status) used to display your account state in the interface. Updated on each sign-in; cleared on sign-out.

These are strictly necessary for the Service to function. Without them, you would need to enter your credentials on every page load.

B. Notice Preferences

We store a single preference flag in localStorage to remember that you have acknowledged the technology notice banner, so that the banner is not shown again on subsequent visits.

This flag does not contain personal data. It is retained until cleared by the user, either by clearing browser data or through browser Developer Tools.

3. What We Do NOT Use

Omnisc does not use:

  • analytics cookies or scripts (e.g., Google Analytics, Mixpanel, Hotjar, or similar);
  • marketing or advertising cookies;
  • tracking pixels or web beacons;
  • third-party cookies set by Omnisc;
  • fingerprinting or cross-site tracking technologies;
  • sessionStorage for non-essential tracking or profiling purposes;
  • any non-essential cookies or similar technologies.

4. Third-Party Payment Pages

When you complete a purchase, you are redirected to a third-party payment page operated by Stripe or Lemon Squeezy, depending on your region.

These payment providers may use their own cookies and similar technologies on their checkout pages, including for fraud prevention, security, and payment processing. Omnisc does not control the cookies or tracking technologies used by these third-party services.

For information about how these providers handle cookies and personal data on their pages, please refer to:

  • Stripe: [https://stripe.com/legal/cookies-policy](https://stripe.com/legal/cookies-policy)
  • Lemon Squeezy: [https://www.lemonsqueezy.com/privacy](https://www.lemonsqueezy.com/privacy)

5. Third-Party Email Delivery

Transactional emails sent by Omnisc (such as account setup, password reset, and billing notifications) are delivered through Resend, a third-party email delivery provider.

Resend may use cookies and similar technologies as part of its email delivery infrastructure. For information about how Resend handles cookies and similar technologies, please refer to:

  • Resend: [https://resend.com/legal/cookie-policy](https://resend.com/legal/cookie-policy)

Omnisc does not use email open-tracking pixels or click-tracking for marketing purposes.

6. Why We Do Not Need Cookie Consent

Under the EU ePrivacy framework and its national implementations, strictly necessary cookies and similar technologies that are essential to provide a service requested by the user do not require prior consent.

All client-side storage used by Omnisc falls into the strictly necessary category. We use localStorage for authentication, session management, and essential notice-preference storage — functions that are necessary for the Service to operate as requested by you.

If we introduce non-essential technologies in the future (such as analytics or marketing cookies), we will update this Policy and implement an appropriate consent mechanism before deploying them.

7. How to Manage or Clear Stored Data

You can view, manage, or delete the data Omnisc stores in your browser at any time.

To view stored data:

  • In most browsers: open Developer Tools (F12) → Application tab → Local Storage → select the Omnisc domain.

To clear stored data:

  • Sign out of Omnisc through your Account page — this clears all authentication data stored by Omnisc.
  • Alternatively, you can clear localStorage manually through your browser's Developer Tools or by clearing your browser's site data through browser settings.

Please note: Clearing authentication data will sign you out, and you will need to sign in again to access the Service.

8. Do Not Track

Some browsers offer a "Do Not Track" (DNT) signal. Because Omnisc does not engage in cross-site tracking, behavioral advertising, or profiling, the Service operates the same way regardless of whether a DNT signal is received.

9. Changes to This Policy

We may update this Cookie & Technology Policy from time to time. If we make material changes — particularly if we introduce non-essential cookies or tracking technologies — we will notify you at least 30 days before the changes take effect through the Service, by email, or by other reasonable means.

The updated version will become effective on the date stated at the top of this Policy.
