Cookie Policy

Last updated September 25, 2026

This Cookie Policy explains how Mellow (“Mellow,” “we,” “us,” or “our”) uses cookies and similar technologies when you access or use the Mellow website, web application, digital environments, and related services (collectively, the “Service”).

This policy should be read together with Mellow's Privacy Policy.

1. What Are Cookies?

Cookies are small data files that websites may place on or access through your browser or device.

Cookies and similar technologies can help websites:

  • Keep users signed in
  • Maintain secure sessions
  • Remember preferences
  • Preserve certain settings
  • Detect fraud or suspicious activity
  • Operate authentication and security checks

Cookies may remain on your device for a particular period of time or may disappear when your browser session ends.

Mellow may use cookies or similar technologies. This policy describes what Mellow currently uses; it does not claim that Mellow never uses cookies.

2. Similar Technologies

Mellow may also use technologies that function similarly to cookies.

These may include:

  • Local storage
  • Session storage
  • Browser storage
  • Authentication tokens
  • Device or browser identifiers used for security or session purposes
  • Similar storage or access technologies

For simplicity, references to “cookies” in this policy may also include these similar technologies where appropriate.

3. What Mellow Uses Today

As currently configured, Mellow primarily uses essential technologies to operate the Service.

These may include:

  • Essential authentication and session technologies
  • Password recovery and account-security technologies
  • Browser local and session storage
  • Security, bot-detection, and abuse-prevention technologies
  • Payment technologies used when interacting with checkout or subscription management
  • Authentication technologies used when choosing a third-party sign-in option

These technologies are used to provide functionality you request, secure accounts, and keep the Service working — not to operate advertising tracking.

4. Essential Cookies and Storage

Some cookies or similar technologies are necessary for Mellow to function properly.

These may be used for purposes such as:

  • User authentication
  • Session management
  • Account security
  • Bot and abuse prevention
  • Subscription access
  • Maintaining requested settings
  • Technical operation of the Service

Because these technologies may be necessary to provide functionality you request, they may not always be optional.

Blocking essential cookies or related storage may prevent some parts of Mellow from working correctly.

5. Authentication Technologies

Mellow uses authentication and account-management providers, together with cloud hosting, database, storage, and application-infrastructure providers, to support account access. Authentication-related technologies may help:

  • Determine whether you are signed in
  • Maintain your authenticated session
  • Protect your account
  • Support password reset and email confirmation flows
  • Connect your browser session to your Mellow account

These technologies may be necessary for users who access account-based functionality.

Mellow may also use security, bot-detection, and abuse-prevention technologies on certain authentication forms. Those technologies may use cookies or other browser storage as part of security verification.

6. Google Sign-In

If you choose Sign in with Google, Google and Mellow may use cookies, authentication tokens, or similar technologies necessary to complete and maintain the authentication process.

Google may independently place or access cookies according to its own services and privacy practices.

Mellow does not control cookies placed independently by Google outside Mellow's own systems.

7. Subscription and Payment Technologies

Mellow uses Stripe to provide subscription payment and billing functionality.

When you interact with Stripe-hosted checkout, billing management, or payment interfaces, Stripe may use cookies or similar technologies for purposes that can include:

  • Payment processing
  • Fraud prevention
  • Security
  • Authentication
  • Subscription management
  • Maintaining payment-session functionality

Stripe's use of those technologies is also governed by its own privacy and cookie practices.

8. Functional / Local Product Storage

Mellow may use browser storage to remember choices you make and to keep certain product state on your device.

These may include:

  • Sound mixer / audio preferences
  • Volume preferences
  • Room preferences
  • Interface preferences
  • Display settings
  • Navigation state
  • Timer preferences
  • Tasks and related local task state
  • Certain progress, unlock, or acknowledgment preferences
  • Other customization or session settings

Functional and local storage helps Mellow provide a more consistent experience when you return. Some of this information may exist only on your device and not on Mellow's servers.

9. Local Storage

Mellow may use browser localStorage for information that should remain available after a browsing session ends.

Depending on how Mellow is configured, local storage may be used to retain things such as:

  • User preferences
  • Interface settings
  • Audio preferences
  • Temporary room settings
  • Tasks and other local application state
  • Other non-sensitive information used to improve your experience

Information stored in local storage generally remains until it is removed by the application, the user, or the browser.

10. Session Storage

Mellow may use browser sessionStorage to maintain information during a particular browser session.

Session storage may be used for:

  • Temporary application state
  • Navigation state
  • Temporary settings
  • Short-lived user-interface information

Session storage generally expires when the relevant browser tab or session is closed.

11. Analytics Cookies

Mellow does not currently operate a dedicated analytics tracking SDK and does not currently use analytics cookies as part of the Service.

If analytics tools are introduced later, this Cookie Policy will be updated, and where applicable law requires consent before non-essential analytics technologies are used, Mellow will request that consent.

12. Advertising Cookies

Mellow does not currently use advertising cookies or advertising trackers.

Mellow does not currently rely on personalized third-party advertising as a core part of the Service.

If Mellow introduces advertising, behavioral advertising, retargeting, advertising pixels, or similar technologies in the future, this Cookie Policy will be updated as appropriate, and where required by law users will be provided applicable consent or opt-out choices.

13. Cookie Consent Banner

Mellow does not currently display a cookie-consent banner, because the Service does not currently operate optional analytics or advertising tracking cookies.

Essential authentication, session, security, and local product-storage technologies may still operate because they are needed to provide the Service you request.

If optional non-essential technologies are added later and consent is legally required, Mellow will seek that consent and may introduce a consent or preference interface at that time.

14. First-Party and Third-Party Cookies

Cookies used in connection with Mellow may be either:

First-Party Cookies

These are associated directly with Mellow and may be used to provide core website or application functionality.

Third-Party Cookies

These are associated with services provided by other companies, such as authentication, payment, security, cloud infrastructure, or other technology providers (for example, Stripe or Google where you interact with those services).

Third parties may control how their own cookies operate.

15. Session and Persistent Cookies

Mellow may use both session cookies and persistent cookies.

Session Cookies

These generally last only for the duration of a browser session.

They may help maintain temporary functionality while you use the Service.

Persistent Cookies

These may remain on your browser or device after you close the browser.

They may be used to remember preferences, login status, or other information between visits.

The duration of a persistent cookie varies depending on its purpose and configuration.

16. Browser Controls

Most browsers allow you to manage cookies through browser settings.

Depending on your browser, you may be able to:

  • View stored cookies
  • Delete individual cookies
  • Delete all cookies
  • Block cookies
  • Block third-party cookies
  • Receive warnings before cookies are stored
  • Automatically delete cookies when the browser closes

The exact controls depend on your browser.

Blocking or deleting cookies may affect Mellow functionality.

For example, you may:

  • Be signed out
  • Lose saved browser preferences
  • Need to authenticate again
  • Lose temporary settings
  • Experience reduced functionality

17. Clearing Browser Storage

Your browser may also allow you to clear:

  • Local storage
  • Session storage
  • Site data
  • Cached files
  • Other stored website information

Clearing this information may reset certain Mellow settings or remove locally stored application information on that device.

Account information that has already been stored with Mellow's servers may not be deleted merely by clearing browser storage.

Likewise, deleting a Mellow account does not necessarily erase local browser storage on every device you have used.

18. Global Privacy Control and Similar Signals

Certain browsers or extensions may transmit privacy preference signals, including Global Privacy Control or similar mechanisms.

Where applicable law requires Mellow to recognize a particular legally valid opt-out preference signal, Mellow will endeavor to honor that signal as required.

The effect of such signals may depend on:

  • Your jurisdiction
  • The browser or extension used
  • The technologies currently implemented by Mellow
  • The type of data processing involved

19. Do Not Track

Some browsers provide a “Do Not Track” setting.

There is not a single universally adopted standard governing the meaning or required response to all Do Not Track signals.

Mellow may therefore not respond to traditional Do Not Track signals unless applicable law requires otherwise.

This is separate from legally recognized opt-out preference signals that Mellow may be required to honor.

20. Third-Party Services

Third-party providers used by Mellow may independently use cookies or similar technologies. These providers may include services used for authentication, payment processing, cloud infrastructure, security, bot and abuse prevention, email delivery, customer support, and other functionality necessary to operate the Service. Their technologies may be governed by their own privacy and cookie practices.

21. Duration of Cookies

The amount of time a cookie remains on your device depends on its purpose and configuration.

Some cookies may expire:

  • When you log out
  • When you close your browser
  • After a defined period
  • When you manually delete them

Others may remain longer to maintain preferences or functionality.

Mellow will not intentionally retain cookies longer than reasonably necessary for their stated purpose.

22. Data Collected Through Cookies

Depending on the cookie or technology, information collected may include:

  • Session identifiers
  • Account authentication status
  • Browser information
  • Device information
  • IP address
  • Approximate geographic region
  • Date and time information
  • Application settings
  • Error information
  • Security-check information

The information collected depends on which technologies are active.

23. Sensitive Information

Mellow does not intend to use cookies or tracking technologies to build advertising profiles based on sensitive medical or mental-health information.

Mellow's focus and relaxation features do not mean that users are categorized as having ADHD, a medical condition, or a mental-health condition.

Users should not provide sensitive health information through Mellow unless a feature specifically and lawfully requests it.

24. Children

Mellow is intended for users 18 years of age or older.

We do not intentionally use cookies to create behavioral advertising profiles of children.

If we learn that our Service is being used in a manner that creates additional obligations concerning children's privacy, we will take appropriate steps to address those obligations.

25. Changes to Technologies We Use

Mellow is an evolving service.

We may:

  • Add service providers
  • Remove service providers
  • Change authentication systems
  • Add analytics in the future
  • Change performance tools
  • Modify browser-storage practices
  • Add new functionality

If those changes materially alter our cookie or tracking practices, we will update this Cookie Policy and, where required, obtain appropriate consent.

26. Changes to This Cookie Policy

We may update this Cookie Policy periodically.

When we do, we will update the Last Updated date at the top of the policy.

If a material change requires additional notice or consent under applicable law, we will provide that notice or obtain that consent as required.

27. Relationship to the Privacy Policy

This Cookie Policy supplements Mellow's Privacy Policy.

The Privacy Policy provides additional information about:

  • Information we collect
  • How we use information
  • How information is shared
  • Data retention
  • Security
