Plans start at $9.99/month billed annually.
GhostMyDataGhostMyData's answer:
More coverage (1,500+ brokers), lower price ($9.99/mo vs $14.98 for Incogni), free scan with 3 free trial removals (no credit card), family plans covering 5 members, and transparent compliance reporting. We also use dual search engines (Google + Brave) to find exposures competitors miss.
GhostMyData's answer:
We cover 1,500+ data broker sites — 3.5x more than Incogni and 17x more than DeleteMe's auto-removal. We send legally-enforceable CCPA deletion requests, not just opt-out forms. And we publish a live broker compliance report showing which brokers actually delete your data and which ignore requests.
GhostMyData's answer:
Privacy-conscious individuals and families who want their personal data removed from people-search sites and data brokers. Also businesses protecting employees from social engineering attacks that exploit exposed personal data.
GhostMyData's answer:
I discovered my full name, home address, phone numbers, and family members' details were publicly listed on hundreds of people-search sites — available to anyone for under a dollar. After spending 40+ hours manually submitting opt-out forms, I realized the data just comes back. So I built GhostMyData to automate the entire process.
GhostMyData's answer:
Next.js, React, TypeScript, Prisma ORM, PostgreSQL, Vercel, Resend for transactional email, Amazon SES for broker CCPA emails, Google and Brave Search APIs for exposure detection.
GhostMyData's answer:
I built GhostMyData because I was tired of finding my personal information — home address, phone numbers, family members — plastered across dozens of data broker sites. After trying other services, I realized most only cover a fraction of brokers and charge premium prices for basic scans. GhostMyData scans 1,500+ data broker sites, sends legally-backed CCPA deletion requests on your behalf, and tracks every removal to completion. The automated removal pipeline handles everything from opt-out form submissions to verification that your data was actually taken down. We also offer family plans so you can protect your entire household under one subscription, and our daily privacy digest keeps you informed without email overload. The whole platform is designed around transparency — you see exactly what was found, what's been removed, and what's still in progress.

I have a Project Euler (https://projecteuler.net/) account. Though I do not register at all on the leader board I will sometimes work obsessively on a problem just to make one of the level icons light up for me. There is not really competition just a tiny reward. - Source: Hacker News / 9 months ago
I do hobby programing. It is sometimes to create something (supposedly) useful. Lately though it is more discovery and a little math like. I enjoy Project Euler (https://projecteuler.net/. Recently I have been playing with superpermutations (https://projecteuler.net/) and pencil and paper is useful but filling lots of paper with lots of numbers is not that fun. - Source: Hacker News / over 1 year ago
