This Cookie Policy explains how My Weather ("we", "us", or "our") uses cookies and similar technologies when you use our application. By using our Service, you consent to the use of cookies as described below.
1. What Are Cookies?
Cookies are small text files placed on your device by websites and applications. They are widely used to make services work efficiently, remember your preferences, and provide analytics. "Local storage" and "session storage" are similar browser technologies that serve the same purpose.
2. What We Store and Why
2.1 Essential (Strictly Necessary)
These are required for the Service to function. You cannot opt out of these.
mw-user (Local Storage) — Your user session data (name, preferences, city list). Enables the app to work and remember your settings between visits.
mw-cookie-consent (Local Storage) — Records whether you accepted or declined cookies, so we don't show the banner again.
Firebase Auth tokens (Local Storage) — Authentication session tokens managed by Firebase. Required for account login persistence.
2.2 Functional
These enhance your experience by remembering your choices.
mw-lang (Local Storage) — Your preferred language setting (e.g., "en", "ru").
mw-theme (Local Storage) — Your dark/light theme preference.
mw-unit (Local Storage) — Temperature unit preference (Celsius/Fahrenheit).
mw-humor (Local Storage) — Your selected humor style for AI commentary.
These help us understand how the Service is used so we can improve it.
Firebase Analytics cookies (_ga, _gid, and related) — Collect anonymized and aggregated usage data such as pages visited, session duration, and device type. No personally identifiable information is collected through these cookies. Data is processed by Google under the Firebase Privacy Policy.
2.4 Push Notification
OneSignal identifiers (Local Storage / IndexedDB) — Device tokens and subscription state for delivering push notifications. Managed by OneSignal under their Privacy Policy. Only active if you have enabled push notifications.
3. Third-Party Cookies
We do not serve advertising cookies. The only third-party cookies come from:
Cloudflare: Security and performance (may set __cf_bm or similar cookies for bot detection)
We do not allow any third party to use cookies on our Service for advertising or cross-site tracking purposes.
4. How Long Do Cookies Last?
Session cookies: Deleted when you close your browser.
Persistent cookies: Remain on your device until they expire or you delete them. Most of our local storage data persists until you clear browser data or delete your account.
Analytics cookies: Typically expire within 2 years (Google Analytics standard).
5. Your Choices
You have several options for managing cookies:
Cookie banner: When you first visit, you can accept or decline non-essential cookies.
Browser settings: Most browsers allow you to block or delete cookies. Note that blocking essential cookies may prevent the Service from functioning properly.
Clear data: You can clear all stored data by using your browser's "Clear site data" feature.
Delete account: Deleting your account removes all server-side data. Local storage can be cleared via your browser.
6. What Happens If You Decline?
If you decline cookies:
Essential cookies (session, consent record) will still be used — they are necessary for the Service to work.
Analytics cookies will not be loaded.
The core weather functionality will continue to work normally.
7. Changes to This Policy
We may update this Cookie Policy from time to time. Changes will be posted on this page with an updated date. Continued use of the Service after changes constitutes acceptance.
