Questions, answered

Is this a medical diagnosis?
No. istPositive is an educational reading of an at-home test photo — not a clinical diagnosis. See our disclaimer.
How accurate is it?
The confidence score is a model estimate based on band visibility. It is not a substitute for a clinician. For any clinical decision, consult a doctor.
Where do my photos go?
EXIF metadata is stripped on upload. Images are processed by Anthropic for the analysis only and deleted unless you have a paid plan that opts into history. See /privacy.
Can I use this for blood tests?
Not yet. istPositive currently supports photo readings of urine pregnancy tests only.
What if I'm not sure about my test?
Try multiple angles in good, even daylight. Wait the full read-window listed on your test packaging. If you're still unsure, consult a doctor.
How much does it cost?
Reads are free with no account. Saving and history start at the prices listed on /pricing.
Is my data sold?
No. We do not sell your data, ever. Details on /privacy.
Can I delete my data?
Yes — paid users can delete saved readings any time from your account.
