billfox works without accounts and without tracking.
What we store: your language preference (a cookie) — nothing else about you.
What we compute: comparisons run on official federal premium data and curated tariff tables, directly from your inputs. Your inputs are not saved.
Uploaded documents: photos are processed in memory to read tariff facts and immediately discarded. They are never written to disk. Anonymous tariff facts (provider, plan, price — never names or policy numbers) may be kept to improve our price data.
We never sell data. We take no money from insurers.
