Cookie Policy
Last updated: April 20, 2026
This Cookie Policy explains what cookies and similar browser storage technologies Subblink (“Subblink,” “we,” “us,” or “our”) uses when you visit or interact with the Subblink web application at subblink.co (the “Service”). It also explains what we deliberately choose not to use. We keep things simple: the only cookies on Subblink are the ones required to keep you securely logged in.
This policy should be read alongside our Privacy Policy and Terms of Service.
1. What Are Cookies and Similar Technologies?
Cookies are small text files a website places on your device (computer, tablet, or phone) through your web browser. They are a standard mechanism used across the internet to make websites function correctly, maintain login sessions, and remember user preferences.
localStorage is a browser-based storage mechanism that allows a website to save small pieces of data on your device. Unlike cookies, localStorage data is not automatically sent to the server with every request — it stays on your device unless JavaScript explicitly reads and transmits it.
sessionStorage works like localStorage but is automatically cleared when you close the browser tab. Subblink does not currently use sessionStorage.
Each of these technologies stores only text-based data and can be viewed, modified, or deleted through your browser’s built-in settings or developer tools.
2. Our Approach: Essential Cookies Only
Subblink uses a strictly-essential-only cookie strategy. Every cookie we set is required for the Service to function — specifically, to authenticate you and maintain your session securely. We do not set any cookies for advertising, marketing, analytics, personalization, or third-party tracking purposes.
Because we use only essential cookies, there is no cookie consent banner on Subblink. Under the EU ePrivacy Directive (Directive 2002/58/EC, as amended), the UK Privacy and Electronic Communications Regulations, and equivalent regimes in other jurisdictions, cookies that are strictly necessary for a service the user has explicitly requested are exempt from the requirement to obtain prior consent. Our cookies fall squarely within this exemption.
If we ever introduce non-essential cookies in the future (see Section 7), we will implement a consent mechanism before any such cookies are set.
3. Cookies We Use
All cookies set by Subblink are first-party, essential authentication cookies managed by Supabase, our authentication and database provider.
| Name | Type | Purpose | Duration |
|---|---|---|---|
sb-igowdymesyporhpxsozo-auth-token | Essential (first-party) | Supabase authentication session token. Identifies you as a logged-in user and maintains your session securely across page loads and browser tabs. For larger sessions, this cookie may be split into suffixed chunks (for example, ...auth-token.0, ...auth-token.1). | Session / up to 7 days |
sb-igowdymesyporhpxsozo-auth-token-code-verifier | Essential (first-party) | PKCE (Proof Key for Code Exchange) code verifier used during the OAuth login flow with Google or Microsoft, and during magic-link sign-in. Required for secure, industry-standard authentication. | Temporary — automatically cleared once the login handshake completes |
Notes
- These cookies are scoped exclusively to the
subblink.codomain and are never shared with third parties. - Authentication tokens are transmitted only over encrypted HTTPS connections (TLS 1.2 or higher).
- No cookie set by Subblink contains personally identifiable information such as your name, email address, or payment details.
4. Local Storage
We use your browser’s localStorage to remember a small number of non-sensitive interface preferences so that the dashboard feels consistent as you navigate between pages. These values exist solely on your device and are never transmitted to our servers.
| Key | Purpose | Contains Personal Data? |
|---|---|---|
| Sidebar collapse state | Remembers whether you collapsed or expanded the dashboard sidebar | No |
| Table sort preferences | Remembers your preferred column sort order on the subscriptions table | No |
| Dashboard filter state | Preserves active filters (for example, by vendor or billing frequency) across page navigations | No |
Important
- None of these values contain account credentials, email content, financial information, or any data that could identify you.
- Clearing your browser data or deleting these localStorage entries will simply reset the preferences to their defaults. No functionality is lost.
- We do not use localStorage to fingerprint your device, build behavioral profiles, or track you in any way.
5. What We Do NOT Use
Transparency means being explicit about what we reject, not just what we accept. Subblink does not use any of the following:
- Advertising or marketing cookies. We do not serve ads. We do not set cookies from advertising networks such as Google Ads, Meta Pixel, Amazon Ads, or any other ad platform. We never will.
- Third-party analytics or tracking scripts. We do not embed Google Analytics, Mixpanel, Segment, Hotjar, Heap, Amplitude, FullStory, or any similar service that tracks your behavior on our site or across the web.
- Cross-site tracking. We do not participate in cross-site tracking consortiums or share cookie data with other domains. No data from Subblink is used to track you on any other website.
- Browser fingerprinting. We do not use canvas, WebGL, audio, font, or any other fingerprinting technique designed to identify your device without cookies.
- Social media trackers. We do not embed social media widgets, “Like” buttons, share buttons, or login plugins from Facebook, X, LinkedIn, or any social network that would allow those platforms to track your visit.
- Retargeting or remarketing pixels. We do not use tracking pixels to follow you after you leave Subblink in order to serve you targeted advertising elsewhere.
- Session replay tools. We do not record your mouse movements, clicks, scrolls, or keystrokes using tools like Hotjar, FullStory, or LogRocket.
6. Managing and Deleting Cookies
You are always in control of the cookies and localStorage data on your device.
Authentication Cookies
You can delete Subblink’s authentication cookies at any time through your browser’s cookie settings. Doing so will log you out of Subblink; you will need to sign in again on your next visit.
localStorage Data
You can clear localStorage entries through your browser’s developer tools (typically under Application → Local Storage → subblink.co). Clearing these entries resets your dashboard UI preferences to their defaults. No account data or subscription information is affected.
Browser-Level Controls
Most modern browsers give you granular control over cookies. Common options include:
- Viewing all cookies stored for a specific website
- Deleting individual cookies or clearing all cookies at once
- Blocking cookies from specific domains or all domains
- Configuring separate rules for first-party and third-party cookies
- Automatically clearing cookies when you close the browser
For detailed instructions, consult your browser’s help documentation: Chrome, Firefox, Safari, Edge.
Because Subblink uses only essential cookies, blocking or deleting them will not degrade your experience in unexpected ways — it will simply end your current session.
7. Future Changes
If we ever decide to introduce analytics, performance measurement, or any non-essential cookies or tracking technologies, we commit to:
- Updating this Cookie Policy before any new cookies are deployed.
- Implementing a clear consent mechanism (such as a cookie banner) that lets you opt in or opt out before any non-essential cookies are set on your device.
- Notifying existing users of the change through our standard notification process (see our Privacy Policy).
- Never setting non-essential cookies by default. Any future consent mechanism will default to “declined” until you make an active choice.
