PGPP (Pretty Good Phone Privacy) – a new type of mobile privacy service
Hi, we're Barath and Paul. We co-founded INVISV to build Pretty Good Phone Privacy (PGPP) [https://invisv.com/pgpp], an app and service that provides mobile identifier privacy (IMSI) and Internet privacy (IP) so that neither we nor other providers learn your network identity. We've been thinking about how phones are tracking devices in disguise (at a few layers) and what we can do about it. But the problem is that mobile networks are hard to change, and existing companies are reluctant to change things. A couple years ago we had the idea that we could decouple your identity…
PGPP (Pretty Good Phone Privacy) – a new type of mobile privacy service launched on August 9, 2022 with 21 votes, #861 of 3,307 launches that month and more than 75% of that year's launches. The site was not reachable when checked in September 2026.
In plain words
PGPP is an app and service that masks mobile phone identities (IMSI) and IP addresses to prevent mobile operators and other providers from learning a user's network identity. Built by INVISV, it separates user identity from the SIM card, allowing mobile service to continue while maintaining privacy at the network level. The service is designed for people concerned about phones functioning as tracking devices.

Hey HN, I've been working on https://pornpen.ai, a site for generating adult images. Please only visit the site if you are 18+ and willing to look at NSFW images. This site is an experiment using newer text-to-image models. I explicitly removed the ability to specify custom text to avoid harmful imagery from being generated. New tags will be added once the prompt-engineering algorithm is fine-tuned further. If the servers are overloaded, take a look at the feed and search pages to look through past results. For comments/suggestions/feedback please visit…
