FattyOps is a subscription software service delivered over text message. You tell it what you eat; it does arithmetic and sends you information about it. It is operated by David Moss as a sole proprietor in Kirkland, Washington.
It is not medical advice and it is not a clinician. Nothing it says diagnoses, treats, or prevents anything. It does not know your medical history beyond what you tell it, and it can be wrong — it will tell you when it has been. Anything clinical goes to an actual doctor. If you are struggling with disordered eating, the NEDA helpline in the US is 1-800-931-2237.
$12.99 per month, billed monthly through Stripe, renewing until you cancel. Prices may change with at least 30 days' notice by text.
Text CANCEL to the number. We reply asking you to confirm; you confirm; it is done. Billing stops immediately and you keep access through the period you already paid for. No forms, no phone call, no retention offers. Text STOP to end all messages at any time, which also cancels.
Text DELETE and everything you have given us is erased within 30 days, including from our processors. See the Privacy Policy and the Consumer Health Data Policy.
One person per subscription. Do not use the service to harass anyone, including yourself. We may end an account that does, and refund the unused part.
The service is provided as-is. Decisions about what you eat are yours. Our total liability is limited to what you have paid us in the previous twelve months.
