The problem

Most eligible Canadians
never claim a cent

If you have a Celiac diagnosis, you're entitled to claim the extra cost of gluten-free food as a medical expense on line 33099 of your T1 return. The eligible amount adds to your total medical expenses for the year.

Most people never claim it — not because they're ineligible, but because tracking every receipt and calculating the price difference for every GF item is genuinely overwhelming. Celiac Sentry does that work for you.

Why Celiac Sentry

Everything the CRA spreadsheet
nightmare was missing

No manual entry
AI reads your receipt and identifies gluten-free items automatically — no tapping through every line item yourself.
Defensible claim amounts
Statistics Canada provincial average prices come pre-loaded, so your per-gram comparisons rest on a published, citable reference rather than guesswork.
Audit-ready PDF
Export a professional document with every receipt itemized, your calculation methodology explained, and CRA filing instructions included.
Smart Item Memory
Once you've entered a product's weight and category, Celiac Sentry applies it to that item on later receipts — so the groceries you buy week after week take less work each time.
Privacy by design
Receipt images are processed by Anthropic's commercial AI — which contractually cannot retain or train on your data. We chose them specifically for this.
Built for all of Canada
Available in English, Français, and ਪੰਜਾਬੀ, so more Canadian households can track their claim in the language they're most comfortable with.

FAQ

Common questions

To claim GF food expenses on line 33099, you need a formal Celiac disease diagnosis and a letter from a licensed physician confirming your need for a gluten-free diet. Celiac Sentry handles the record-keeping — your doctor handles the letter. Always confirm your eligibility with a qualified Canadian tax professional before filing.
The CRA requires you to calculate the price difference between what you paid for a gluten-free product and what you would have paid for the regular equivalent. Celiac Sentry uses Statistics Canada provincial average prices as the reference — the method recommended by Celiac Canada and accepted by the CRA. The eligible amount is the GF price minus the regular price, calculated per gram.
Yes. Receipt images are sent to Anthropic's commercial AI (US-based) for processing — Anthropic is contractually prohibited from retaining your images or training on your data.

Both plans include identical features — full AI receipt scanning, Statistics Canada prices, PDF export, Smart Item Memory, and all languages. The difference is billing: the annual plan ($29.99/year) includes a 7-day free trial and works out to about $2.50/month. The monthly plan ($3.99/month) bills immediately with no free trial. The free trial is available once per Google account.
Cancel anytime through your Google Play account (Google Play → profile icon → Payments & subscriptions → Subscriptions). Access continues until the end of your current billing period. No penalties, no questions asked.
No. Celiac Sentry is a tracking and documentation tool only — not a tax filing service, accounting service, or medical service. Calculations are estimates based on publicly available CRA guidance. Always consult a qualified Canadian tax professional before filing your return. A formal Celiac diagnosis from a licensed physician is required by the CRA to claim this deduction.
