1. Introduction
This Cookie Policy explains how Servalian ("we", "us", or "our") uses cookies and similar technologies to recognize you when you visit our website at servalian.com ("Website"). It explains what these technologies are and why we use them, as well as your rights to control our use of them.
3. How We Use Cookies and Browser Storage
We use a minimal amount of cookies and browser storage on our website. We do not use any cookies for advertising, marketing, or cross-site tracking.
Cookies
We use a single essential cookie that is necessary for the site to function securely:
| Name | Type | Purpose | Duration |
|---|---|---|---|
| session_token | Essential | Unique session identifier for API authentication and rate limiting. httpOnly, secure, and scoped to our domain | 24 hours |
Local Storage
We store a small number of preferences and identifiers in your browser's local storage:
| Name | Type | Purpose | Duration |
|---|---|---|---|
| theme | Preference | Remembers your preferred theme (light/dark mode) | Until manually cleared |
| snow | Preference | Remembers your preference for the seasonal snow effect | Until manually cleared |
| srv_dismissed | Functional | Remembers that you have dismissed the privacy transparency notice | Until manually cleared |
| vs_uid / vs_uid_ts | Analytics | Anonymous visitor identifier and timestamp set by Vulpasoft, our privacy-focused analytics provider. Not linked to any personal information | Until manually cleared |
Session Storage
Session storage is cleared automatically when you close the browser tab:
| Name | Type | Purpose | Duration |
|---|---|---|---|
| srv_fbm | Functional | Prevents the feedback prompt from showing repeatedly within the same tab | Tab session |
| vs_tab | Analytics | Tab-level session identifier for Vulpasoft analytics | Tab session |
Analytics
We use Vulpasoft, a privacy-focused analytics platform. Vulpasoft does not use cookies and does not collect personally identifiable information. It stores a minimal anonymous visitor identifier in localStorage to understand how visitors use our website. Vulpasoft does not track you across other websites and does not build advertising profiles.
4. Tool-Specific Storage
When you actively use our web-based tools, additional data is stored locally in your browser for functionality purposes. This data is only created when you use the respective tool and does not contain tracking information:
| Tool | Storage Type | What Is Stored | Purpose |
|---|---|---|---|
| Koppie / Shed / Dawn | sessionStorage | OAuth CSRF state parameters, PKCE verifiers | Security during authentication flows (cleared after use) |
| Dawn | localStorage | Session identifier, return URL | Maintaining your session across page navigations within the tool |
| Purr | localStorage | Upvote state | Remembers whether you have upvoted a generated page to prevent duplicate votes |
Security-related items (OAuth state, PKCE verifiers) are ephemeral and are automatically cleared after the authentication flow completes. Groom does not store any data in your browser.
5. Your Choices
You have control over the data stored in your browser:
- Essential cookies cannot be disabled as they are necessary for site security and functionality
- You can clear all locally stored preferences and data through your browser's settings
- You can use your browser's private or incognito mode to browse without persistent storage
- Tool-specific data can be cleared individually through your browser's developer tools or storage settings
- We do not use any marketing or advertising cookies, so there is nothing to opt out of in that regard
