Eight UK grocers, one badge system
Sugar Tracker overlays a small badge on each product on the listing and detail pages of:
Threshold presets — UK FSA traffic-light by default
Out of the box, sugar, salt, and saturates use the official UK Front-of-Pack thresholds. Health Modes in the popup swap in tighter bands for one nutrient at a time — Reduced-Sodium, Reduced-Sugar, Reduced-Saturates — and the badge, tooltip and Nutrition Guide all follow whichever preset is active. The defaults:
Calories use a published composite band (low ≤ 40 kcal, high > 275 kcal per 100g); the FSA does not publish a calorie traffic-light.
Early access — Reduced-Sugar and Reduced-Saturates
Two Health Modes are built and shipping in the extension but are not yet selectable: Reduced-Sugar and Reduced-Saturates. They tighten the bands for one nutrient while the other three stay on the FSA defaults, for shoppers actively cutting one thing rather than reading every label.
- Reduced-Sugar — low ≤ 0.5g, high > 5g per 100g. Source: EU Reg 1924/2006 Annex “sugars-free” plus the UK FSA low/medium boundary.
- Reduced-Saturates — low ≤ 0.1g, high > 1.5g per 100g. Source: EU Reg 1924/2006 Annex “saturated fat-free” plus the UK FSA low/medium boundary.
Nothing is charged and there is no sign-up. If you want either mode switched on, say so on the feedback form — that is the only route, and the extension itself sends nothing.
Privacy-first by design
- No sign-up, no account, no external servers.
- Settings live in
chrome.storage.sync; the nutrition cache and a capped record of products you have already seen live inchrome.storage.local. Neither is ever uploaded. - No analytics, no telemetry, no third-party SDKs.
- Diagnostics export is local-only — pasted into a feedback form by the user, never auto-sent.

Source & support
Sugar Tracker is proprietary and the code repository is private, so the source is not publicly browsable today. Unminified source is supplied to Chrome Web Store reviewers on request, and the privacy claims on this page are verifiable against the extension's declared permissions on its store listing.
Bug reports and feature requests are welcome on the issue tracker, which is also where the extension's “Report this site” button sends you.
