KEY FEATURES
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

PRICE HISTORY CHARTS
A full price history graph is injected directly on every Tesco product page — lowest, highest, and average price over the last 30 days. No extra tab, no separate website required.

PRICE-DROP ALERTS
Set a target price for any product and receive an email the moment Tesco drops below it. Alerts are stored on your account — not just in the browser. They survive reinstalls, browser changes, and device switches.

ACCOUNT SYNC
Sign in once and your entire alert list follows you across Chrome, Firefox, and Edge. No manual export or import needed.

CLUBCARD PRICE VISIBILITY
Track both the standard shelf price and the Clubcard member price side by side. Instantly see which products reward Clubcard holders most.

BILINGUAL INTERFACE (EN / HU)
Full English and Hungarian interface. Switch with one click in the popup header. Your preference is saved automatically.

🌙 DARK & LIGHT THEME
The popup and in-page chart panel respect your chosen theme and remember it between sessions.

PRIVACY-FIRST
No trackers, no ads, no affiliate links, no data selling. All data lives on the Gavaller infrastructure or your own self-hosted backend.
