Cookie Policy
Last updated: 19 July 2026
This Cookie Policy explains how Accounting Tutor AI ("we", "us", "our") uses cookies and similar technologies when you visit accountingtutorai.com or use the Service. It should be read alongside our Privacy Policy.
1. What Are Cookies?
Cookies are small text files placed on your device when you visit a website. They let the site remember information about your visit, keep you signed in, and measure how the site is used. Similar technologies include browser local storage and session storage. In this policy, "cookies" covers all of these.
2. Categories of Cookies We Use
2.1 Strictly necessary (always on)
These cookies are required for the Service to work. They authenticate you, keep your session active, protect against fraud and abuse, and remember your cookie consent choice. The Service cannot function properly without them, and they are not subject to consent.
2.2 Analytics and performance (only with consent)
These cookies help us understand how visitors interact with the Service — which pages are visited most, how users move through the app, where errors occur — so we can improve it. They are only set after you accept analytics cookies in our cookie banner. We also derive approximate country information from connection headers when you sign in to understand regional usage patterns; this is not collected via cookies and is described in our Privacy Policy.
2.3 Preferences
These cookies remember choices you make (such as your sidebar state, calculator inputs, and study preferences) to make your experience smoother across visits.
3. Cookies We Set
| Name | Category | Purpose | Retention |
|---|---|---|---|
sb-access-token | Strictly necessary | Authenticates your session with our backend. | ~1 hour (refreshed) |
sb-refresh-token | Strictly necessary | Renews your sign-in so you don't have to log in every visit. | Up to 30 days |
cookie_consent_given | Strictly necessary | Remembers whether you accepted or rejected non-essential cookies. | 12 months |
inactivity_logout | Strictly necessary | Flags an inactivity-based sign-out so we can show a notice on the login page. | Session only |
| UI preferences (local storage) | Preferences | Remembers sidebar state, chat thread, and similar UI choices. | Until cleared |
| Analytics identifiers | Analytics (consent required) | Aggregated page-view and feature-use measurement. | Up to 13 months |
Stripe cookies (e.g. __stripe_mid, __stripe_sid) | Strictly necessary (when checking out) | Fraud prevention and secure payment processing on Stripe-hosted pages. | Session – 1 year |
| Google sign-in cookies | Strictly necessary (when using Google login) | Authenticate you via Google OAuth. | Managed by Google |
Specific cookie names may change as the Service evolves. This table is updated on a best-effort basis; the exact cookies set on your device can always be inspected in your browser's developer tools.
4. How to Manage or Withdraw Consent
When you first visit the site you'll see a cookie consent banner where you can Accept all or Reject non-essential cookies. Analytics cookies are only set after you choose Accept all. To change your choice later:
- Open your browser's site data settings for accountingtutorai.com and clear the
cookie_consent_givenentry — the banner will reappear on your next visit so you can choose again; - Or clear all cookies for the site to reset every preference.
You can also block or delete cookies through your browser settings. Note that disabling strictly necessary cookies will prevent you from signing in or using key features of the Service.
5. Third-Party Cookies
Some cookies are set by third parties that appear on our pages. We do not control these cookies; please refer to the providers' own policies for details:
- Stripe — secure payment processing and fraud prevention;
- Supabase — authentication and session management;
- Google — optional Google Sign-In;
- Analytics provider — aggregated usage statistics (only after consent).
6. Changes to This Policy
We may update this Cookie Policy from time to time to reflect changes to the cookies we use or for operational, legal, or regulatory reasons. The "Last updated" date at the top of this page indicates when it was last revised.
