Cookies Policy
Last updated: April 2026
Operated by: [TBD — owner-supplied entity name] (trading as Sentrytex)
Overview
Sentrytex uses a small number of first-party cookies that are strictly necessary to operate the Service. We do not use advertising cookies, third-party tracking cookies, or behavioural analytics cookies.
This page explains exactly what cookies we set, why we set them, and how you can manage them.
Cookies We Set
| Cookie Name | Purpose | Type | Duration |
|---|---|---|---|
sb-*(Supabase auth cookies) | Maintains your authenticated session. Required for you to stay logged in and access the Service. Without this cookie, the Service cannot function. | Session / Authentication | Expires on browser close, or at session timeout (configurable in account settings) |
These cookies are set by our authentication provider, Supabase, on behalf of Sentrytex. They are first-party cookies: they are set on the sentrytex.com domain and are not accessible by third-party sites.
No other cookies are currently set by Sentrytex.
Local Storage
In addition to cookies, we use your browser's localStorage to save your theme preference (dark or light mode) between visits.
This is distinct from a cookie: localStorage data is stored entirely within your browser and is never transmitted to our servers. It contains no personally identifiable information.
You can clear localStorage at any time through your browser's developer tools or settings (usually under “Application” > “Local Storage” in developer tools).
What We Do Not Use
- No third-party tracking cookies.
- No advertising or retargeting cookies.
- No cross-site analytics (e.g., Google Analytics, Mixpanel, Hotjar) as of the date of this policy.
- No social media pixels or sharing widgets.
Managing Cookies
You can control and delete cookies through your browser settings. The steps vary by browser:
- Chrome: Settings > Privacy and security > Cookies and other site data
- Firefox: Settings > Privacy & Security > Cookies and Site Data
- Safari: Preferences > Privacy > Manage Website Data
- Edge: Settings > Cookies and site permissions
Please note: disabling the sb-* authentication cookie will prevent you from logging in to the Service. If you clear your cookies, you will need to log in again.
Changes to This Policy
If we introduce analytics tools, third-party integrations, or any additional cookies in the future, we will update this policy and display a cookie consent banner before setting any non-essential cookies.
We will update the “Last updated” date at the top of this page whenever changes are made.
