Pricing & Billing FAQ
Yes. Macrition's Free plan is genuinely free forever - every calculator, tracking app, and restaurant guide works without an account. Sign up free to save up to 50 diary entries per day, create 10 custom foods, and sync your data across devices.
When you start a Pro trial we ask for a payment method but charge nothing for 14 days. (Premium requires direct payment backed by our 30-day money-back guarantee). You get full access to every feature in that tier immediately. Cancel before day 14 and you won't be billed, your account simply reverts to the Free plan and all your saved data stays intact.
Yes. Cancel from your dashboard at any time with one click, no phone calls, no retention scripts, no exit surveys. Your subscription stays active until the end of the current billing period, then your account reverts to the Free plan and you keep all your saved data, custom foods, and diary history.
If you're not satisfied within 30 days of a paid subscription, email support@macrition.com for a full refund, no questions asked. Annual subscribers can request a prorated refund any time within their billing year for the unused months. Trial periods are always free.
Yes. Upgrading is instant: pick the higher plan on the checkout page and its features unlock as soon as the payment clears, at that plan's normal price. There is no separate downgrade flow - simply cancel and your current plan (and all its features) stays active until the end of the period you have already paid for. Monthly/yearly billing is chosen at checkout and renews at the same cadence.
Pro is built for daily trackers who want unlimited everything: unlimited diary entries, custom foods, bookmarks, recipe import, data export (CSV/JSON), water tracker with goals, custom meal planning, progress photos, weekly summary emails, and an ad-free experience. Premium adds everything an enthusiast or professional needs: 20x more AI coaching capacity, advanced trend analytics with predictions, health metric correlations, custom calculator creation (10 max), API access, personalized supplement recommendations, genetics-aware educational insights, a private AI coaching chat, custom dashboard layouts, meal prep AI planner, grocery list generator, and a nutrition deficiency analyzer.
Yes. Pro yearly is $59.99 (save 37% vs monthly) and Premium yearly is $149.99 (save 37% vs monthly). Annual billing is billed once per year - no monthly charges, no surprises, cancel anytime for a prorated refund of the unused months.
Built on evidence, priced with restraint
No dark patterns, no invented numbers, no fine print. The pricing is built the way the calculators are: checkable.
Calculator inputs stay in your browser. An account exists only for the things that genuinely need a server: sync, history, and AI coaching.
The free tier is a complete product, not a trial. Upgrade only when you outgrow diary history limits or want unlimited AI coaching and API access.
