Prosabe uses only the cookies and browser storage needed to sign you in, keep the Service secure and remember small preferences. We do not use advertising cookies, cross-site tracking or third-party analytics. Because we only use strictly necessary technologies, we do not show a consent banner; if that ever changes, we will ask for your consent first.
1. What This Policy Covers
This Cookie Policy explains how ALCO GROUP LLC ("Prosabe", "we") uses cookies and similar technologies, such as browser local storage, on prosabe.com, optimoeducation.com and the Prosabe web application (the "Service"). It should be read together with our Privacy Policy.
2. What Cookies and Local Storage Are
Cookies are small text files that a website stores in your browser. Local storage and session storage are similar browser features that let a web application keep small pieces of data on your device. In this policy we refer to all of them as "cookies".
3. Cookies We Use
3.1 Strictly necessary
These are essential for the Service to work and cannot be switched off without breaking it. Under the EU ePrivacy rules and similar laws they do not require consent.
| Name / type | Set by | Purpose | Duration |
|---|---|---|---|
sb-…-auth-token (local storage) |
Prosabe, via Supabase | Keeps you signed in and authenticates your requests | Until you log out or the session expires |
Stripe cookies (e.g. __stripe_mid, __stripe_sid) |
Stripe, on its checkout and billing pages | Process payments securely and prevent fraud | Session to 1 year, as set by Stripe |
3.2 Functional
These remember choices you make. They are stored only on your device.
| Name / type | Set by | Purpose | Duration |
|---|---|---|---|
prosabe_pending_plan (local storage) |
Prosabe | Remembers the plan and billing period you selected on the website so they are applied after you sign up | Until used (removed after sign-up) or cleared |
3.3 What we do not use
We do not use advertising cookies, social-media pixels, cross-site tracking, fingerprinting or third-party analytics cookies, and we do not sell or share information collected through cookies.
4. Third-Party Content Loaded by Our Pages
Our pages load fonts from Google Fonts (Google LLC) and icons from the unpkg content delivery network. These services do not set cookies through our pages, but, like any web server, they receive your IP address and browser information when the page loads in order to deliver the files. Stripe's pages, which you reach when you subscribe or manage billing, are governed by Stripe's own cookie and privacy policies.
5. How to Control Cookies
You can delete or block cookies and local storage in your browser settings (for example, in Chrome: Settings → Privacy and security → Third-party cookies / Site data; in Safari: Settings → Privacy; in Firefox: Settings → Privacy & Security; in Edge: Settings → Cookies and site permissions). If you block strictly necessary cookies or local storage, you will not be able to sign in or use the Service.
6. Do Not Track and Global Privacy Control
Because we do not track you across websites or use cookies for advertising, there is no tracking for a "Do Not Track" signal to disable. We treat Global Privacy Control signals as described in our Privacy Policy.
7. Changes
If we start using cookies that require consent, we will update this policy and ask for your consent before setting them. Material changes will be notified as described in our Privacy Policy.
