Cookie and local storage information

PlugTally uses essential browser storage so calculators, guest data and account sessions can work. Optional analytics is controlled separately.

Essential PlugTally storage

• rcc_tariff_v1 — saved electricity price
• rcc_basket_v1 — household basket
• rcc_planner_v1 — planner rows and notes
• rcc_history_v1 — recent calculations
• rcc_preferences_v1 — consent and interface choices
• rcc_account_owner_v1 — helps keep local account data separated between signed-in users

Account-session storage

Supabase stores an authentication session token in the browser after a successful sign-in. This is essential for recognising the signed-in user, refreshing the session and securely requesting only that user’s saved data. Signing out removes the PlugTally account-linked local data from that browser.

Optional analytics

Google Analytics 4 loads only after “Accept analytics” is selected. Rejecting analytics does not stop calculators or account features from working. Preferences can be reopened from the footer.

Removing local information

You can sign out, clear the site’s browser data, or use the account dashboard to clear the cloud-saved PlugTally basket, planner and history. Clearing browser data may also sign you out.
