cookies & local storage
last updated: february 2026
overview
seasons of your life does not use tracking cookies or third-party advertising cookies. we use minimal browser storage to make the service work and to remember your preferences.
cookies
theme preference
we set a single cookie (moonpath_theme) on the .moonpath.dev domain to store your light/dark mode choice. this cookie contains only the value "light" or "dark", expires after one year, and is not used for tracking or analytics. it allows your theme preference to carry over across all moonpath.dev sites.
local storage
the following data is saved in your browser's local storage. it never leaves your device and is not transmitted to any server:
- theme preference: your light/dark mode choice
- authentication session: session data for your signed-in account
- era definitions: custom era names and date ranges you create
- birth information: date, time, and place entered for the star songs feature
- profile metadata: profile names, file labels, and date ranges for your uploaded data
indexeddb
your processed listening statistics (from spotify or apple music) are stored in indexeddb, organized by profile. this allows you to return to your results anytime without re-uploading. you can clear this data from the "my profiles" tab or through your browser settings. this data stays entirely on your device.
only song titles, artist names, album names, play durations, and timestamps are stored. identifying information from export files (such as ip addresses, usernames, and device info) is discarded during processing and never stored.
we request persistent storage from your browser so that your data is not automatically deleted between visits. this does not grant us any additional access to your device. you can revoke this at any time by clearing site data in your browser settings.
what we do not use
- no tracking cookies
- no third-party advertising cookies
- no tracking pixels or beacons
- no fingerprinting
google analytics cookies
google analytics 4 sets the following cookies:
_ga: distinguishes unique visitors. expires after 2 years._ga_[ID]: maintains session state. expires after 2 years.
these cookies do not contain personal information. you can opt out by using the google analytics opt-out browser add-on or by disabling cookies in your browser settings.
session storage
during your visit, traffic source information (referring website, utm campaign parameters, landing page) is stored temporarily in your browser's session storage. this data is automatically cleared when you close your browser tab or browser. it is used solely to attach traffic source context to analytics events and is not persisted between sessions.
analytics
we use both google analytics 4 and vercel analytics. google analytics uses cookies as described above. vercel analytics is privacy-focused and does not use cookies or collect personal data.
stripe
during the payment flow, stripe may set cookies on its own domain (stripe.com) as part of its fraud prevention and payment processing. these cookies are governed by stripe's cookie policy.
managing your data
you can clear all locally stored data at any time through your browser's settings (clear site data for seasons.moonpath.dev). this will sign you out and remove all saved preferences, era definitions, and birth information.
