Cookie Policy
Last updated: July 26, 2026
This Cookie Policy explains how Lumakaizo LLC, the owner and operator of QuotePreview, uses cookies, local storage, and similar browser technologies when you visit our website or use the Service. It should be read together with our Privacy Policy.
1. What cookies are
Cookies are small files stored by your browser. They help websites keep users signed in, remember preferences, secure sessions, and operate reliably. Similar technologies, such as local storage and session storage, can hold preference values on your device without being sent to a server.
2. Everything we store on your device
This is the complete list. It is generated from the same configuration the site uses to decide what to load, so it cannot fall out of step with what actually runs.
| Name | Type | Purpose | Duration | Category |
|---|---|---|---|---|
| sb-*-auth-token | Cookie | Keeps you signed in and protects your account session. | Session / until sign-out | Strictly necessary |
| qp_client_session | Cookie (HTTP-only) | Signs a client in to the client portal to review a shared proposal. | 30 days | Strictly necessary |
| qp_consent | Cookie | Remembers your cookie and advertising preferences. | 12 months | Strictly necessary |
| theme | Local storage | Remembers whether you chose light or dark mode. | Until you clear site data | Preference |
| qp_attribution_v1 | Session storage | Records which campaign link brought you to the site, so a signup can be credited to it. Never used to identify you. | Until you close the tab | Strictly necessary |
3. First-party performance metrics
We measure page loading speed using a first-party endpoint on our own domain. It records the metric name, its value, and the path of the page (for example /blog). It does not record your IP address, your browser's user agent, or any identifier, it sets no cookie, and it is not stored in a database or shared with anyone.
4. Third-party services we connect to
These services receive a request from your browser when you use the relevant part of the site. None of them set advertising or cross-site tracking cookies here.
- Supabase — Hosts our database, authentication, and file storage. Privacy policy for Supabase (opens in new tab)
- Google Fonts — Serves the typeface used across the site. Privacy policy for Google Fonts (opens in new tab)
- Stripe — Processes payments. Loaded only on billing pages. Privacy policy for Stripe (opens in new tab)
- ipify — Returns your IP address when you sign in, so we can show you your own recent session history for account security. Privacy policy for ipify (opens in new tab)
- Google (Gemini) — Generates the AI renders. Used only inside the signed-in app. Privacy policy for Google (Gemini) (opens in new tab)
5. What we do not use
At this time, we do not use:
- Advertising cookies.
- Social-media pixels.
- Third-party cross-site behavioral tracking cookies.
- Analytics products such as Google Analytics.
- Session-recording or session-replay tools.
- Cookies used to sell or share personal information for cross-context behavioral advertising.
If that changes, this page and the notice shown on the site both update automatically from the same configuration, and you will be given controls to turn the new categories off.
6. Managing your choices
You can change your preferences at any time using the cookie preferences control in the site footer. To opt out of any sharing of personal information for cross-context behavioral advertising, see Do Not Sell or Share My Personal Information. We also detect and honor the Global Privacy Control browser signal automatically.
You can additionally configure your browser to block or delete cookies. If you block strictly necessary cookies, signed-in areas and some features will not work. Clearing site data will reset preferences such as your theme choice and your cookie preferences.
7. Changes to this policy
If we add non-essential cookies or materially change our use of browser technologies, we will update this page and provide consent controls where required by law.
