Privacy Policy

We collect only the data you enter: your name, email address, phone number (optional), and blood glucose readings. This data is stored in a secure database (Supabase) with row-level security — only you can read your own data.

We use your email and/or phone number to send reminders and trend alerts at the frequency you choose. You can turn these off at any time in Settings or by replying STOP to any SMS.

We do not sell your data. We do not share it with third parties except the service providers required to operate FASTA1C on our behalf (email delivery via Resend, SMS delivery via Twilio), who may only use it to deliver the service.

SMS opt-in and mobile data: the mobile phone number you provide for SMS reminders, and your consent to receive them, are never shared with or sold to any third party or affiliate for marketing or promotional purposes. This text-messaging opt-in data is used solely to send the reminders you requested and is not shared with third parties for any other purpose.

You can export all your data or delete your account at any time from the Settings page. Deletion is permanent and immediate.

Advertising (Google AdSense)

We use Google AdSense to display advertisements on this site. Google and its third-party vendors use cookies and similar identifiers to serve ads based on your prior visits to this and other websites. Personalized advertising allows Google and its partners to show more relevant ads to you. You can opt out of personalized advertising by visiting Google Ads Settings, or opt out of third-party vendor use of cookies for personalized advertising at aboutads.info/choices. Google's use of advertising cookies is governed by its advertising policies.

Affiliate Disclosure (Amazon Associates)

FASTA1C is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.com. As an Amazon Associate, we earn from qualifying purchases. Affiliate links do not change the price you pay. We only recommend products we believe are useful for diabetes self-management.
