Cookie Policy
Last updated: October 27, 2026
Convenience translation. This page is an English translation of the Turkish original, Çerez Politikası, provided for convenience only. The Turkish version is the binding text and prevails in the event of any discrepancy between the two versions.
This policy explains which cookies and similar storage are used in your browser when you use Seolin, what they do, how long they stay and how you can manage them. Details of how personal data is processed are in the Privacy Policy.
1. Definitions
- Cookie: a small file a site saves in your browser.
- Similar storage: what this policy treats in the same way as cookies: the browser's local storage, session storage and browser database.
2. Categories
| Category | When | Choice |
|---|---|---|
| Strictly necessary | Always | Cannot be switched off: session, security, language and dashboard preferences, the record of your cookie preference |
| Analytics | Only with your consent | Accept, Reject or Settings; off by default |
| Advertising and marketing | — | Not used |
3. Cookies and storage we use
a) Strictly necessary
| Name | Type | What it does | Lifetime |
|---|---|---|---|
seolin_session | Cookie | Keeps you signed in after you sign in | 30 days |
csrftoken | Cookie | Prevents another site from submitting forms on your behalf | About 1 year |
seolin_locale | Cookie | Remembers the interface language you chose (may be set even if you are not signed in) | 1 year |
seolin_site, seolin_range, seolin_sidebar | Cookie | The selected site, date range and menu view in the dashboard (only after sign-in) | 1 year |
seolin_product_analytics_consent | Local storage | Your cookie preference, with the text version and the day it was given | 365 days; then, or when the text changes, we ask again |
seolin:son-ucretsiz-denetim | Local storage | Lets you move your latest free audit to your account later | Not used after 7 days; can stay in the browser until you clear it or start a new free audit |
seolin:setup:<site>:collapsed | Local storage | Your choice to collapse the setup card | Until you clear it |
seolin_locale_unsaved | Session storage | Confirms on the next page a language choice that could not be saved | Until the tab is closed |
A browser setting that is not a cookie: network error reporting (NEL). Cloudflare, which carries our traffic, adds an instruction to our responses so that Chromium-based browsers report to Cloudflare when accessing our site fails. The instruction is valid for 7 days; details are in section 2-g of the Privacy Policy.
b) Analytics (only with your consent)
If you consent, Google Analytics 4 (through Google Firebase) uses the following storage for aggregate visit statistics of our site:
| Name | Type | What it does | Lifetime |
|---|---|---|---|
_ga | Cookie (Google Analytics 4) | Pseudonymous ID that distinguishes your browser | About 2 months (61 days); not extended on later visits; deleted immediately when consent is withdrawn |
_ga_* | Cookie (Google Analytics 4) | Session state | About 2 months (61 days); deleted immediately when consent is withdrawn |
firebase-installations-database, firebase-heartbeat-database | Browser database (Google Firebase) | Firebase installation ID and internal record | If _ga is missing or expired, deleted and recreated before measurement; deleted when consent is withdrawn |
- Google's script is not loaded at all before you consent; if you do not consent, this storage is not written.
- Ad storage and ad personalization are not granted; in Google Consent Mode the advertising signals are always sent as “denied”.
- Page counting on our site is done on the server; it writes no cookie or other storage to your browser and does not identify you.
4. Managing your preference
- On your first visit “Accept”, “Reject” and “Settings” are shown with the same look; no option is preselected. You can use the site without choosing; analytics then does not run.
- You can change your preference later from the “Cookie preferences” link at the bottom of the page or, if you are signed in, from Settings → Privacy.
- Your choice is valid in this browser for 365 days; after that, or if the cookie text changes, we ask again.
- If your browser sends the Global Privacy Control signal, analytics does not run.
- You can also delete cookies and site data in your browser. If you block strictly necessary cookies, you cannot sign in.
5. When you withdraw consent
- New measurement stops immediately; analytics cookies and storage in this browser are deleted. If measurement had started on that page, the page reloads once.
- An event recorded in the few seconds before withdrawal may still be sent because of Google's batched sending.
- Data already sent remains in Google Analytics until its retention period (2 months) ends.
6. Changes and contact
If we update this policy we will change its date. If we start using a new optional cookie, we will update this policy and ask for your consent before starting. Questions: hello@seolin.io.
