safr.

your pass for
safer intimacy.

safr is a personal sexual-health profile. build yours once. when you share it with a partner, the two profiles together produce a compatibility readout — between consenting adults.

closed beta. US only for v0.1. we read every signup.

how it works

01

upload your panel

any standard STI panel — PDF, photo, or screenshot from your patient portal. we extract the results on-device. your file is encrypted before it leaves you.

02

get your profile

a calm, factual summary of your panel. recency, coverage, verification, PrEP status, vaccinations — all on one card. no top-line score, because a profile is yours; it isn't a grade.

03

share, then compare

generate a time-limited link or QR. they don't need an account to view. when they share their profile back, a compatibility readout appears for both of you.

what safr will not do

never tell you what to do.

safr surfaces facts and gaps. it never says ‘go ahead’ or ‘don’t.’ you and your partner decide.

never force disclosure.

any test can be marked ‘withheld’ — viewers see that you tested without seeing the result. especially important for HIV+ users.

never sell your data.

your results are encrypted on your device before they reach our servers. we couldn’t sell them if we wanted to.

never grade you alone.

your profile is yours. compatibility only exists between two people. there is no 0-100 score on a single safr — only when you and a partner compare.

open methodology

we publish exactly how the score is calculated.

trust in a number requires understanding the number. our scoring methodology — every weight, every multiplier, every edge case — is documented publicly and versioned with every card.
