How We Use Cookies
Last updated: June 17, 2026 — This policy explains our use of cookies on mailvault.io.
1. What Are Cookies?
Cookies are small text files that are stored on your device (computer, tablet, or mobile) when you visit a website. They are widely used to make websites work efficiently, improve user experience, and provide information to site owners.
Cookies may be "session cookies" (deleted when you close your browser) or "persistent cookies" (which remain until they expire or you delete them).
2. How MailVault Uses Cookies
We use cookies and similar technologies (such as localStorage) to:
- Keep you signed in to your MailVault account securely.
- Remember your preferences and settings.
- Understand how users interact with the Service to improve it.
- Maintain security and detect fraudulent activity.
- Remember your cookie consent preference (stored in localStorage).
3. Types of Cookies We Use
Essential / Strictly Necessary Cookies
These are required for the core functionality of MailVault.
They include session authentication tokens and security cookies. These cannot be disabled
without breaking core service functionality.
Functional / Preference Cookies
These cookies remember your choices (such as theme preferences or saved settings) to provide
a more personalised experience. Disabling these may reduce functionality.
Analytics Cookies
We may use privacy-respecting analytics (such as anonymised server-side logging) to understand
how users navigate the Service. We do not use third-party behavioural advertising cookies.
LocalStorage
We use browser localStorage to store your cookie consent preference (key: cb).
This is not a cookie but operates similarly and is cleared when you clear your browser data.
4. Third-Party Cookies
MailVault does not use third-party advertising or tracking cookies. We do not share cookie data with advertisers, data brokers, or social media platforms.
If we integrate any third-party services in the future (e.g., performance monitoring), we will update this policy and seek appropriate consent before doing so.
5. Managing & Disabling Cookies
You can control and manage cookies through your browser settings. Most browsers allow you to:
- View cookies stored on your device.
- Delete all or specific cookies.
- Block cookies from specific or all websites.
- Set preferences for certain types of cookies.
Please note that disabling essential cookies will prevent you from signing in to MailVault and using the Service. Instructions for managing cookies can be found in your browser's help documentation:
6. Cookie Consent

You may withdraw consent at any time by clearing your browser's localStorage or cookies for mailvault.io.
7. Cookie Retention Periods
- Session cookies: Deleted when you close your browser.
- Authentication tokens: Typically 30 days, refreshed on activity.
