Savelon

What it does

I've built a private contacts app that I can trust. It is open source, does not collect any data, and stores contacts in encrypted form, hidden from other apps.

Savelon is a privacy-first contacts app. Keep important contacts separate, encrypted, and under your control.

  Hey HN, I built a personal CRM that stores everything in the native iPhone Contacts app instead of another database. The goal was to make the Contacts app I’ve used for years actually useful. I’d love to hear what you think. Especially whether you prefer extending native apps over adopting entirely new tools. Since this is one of the first releases, i would love to get any feedback you have! Alex

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  I built a frontpage for personal blogs▲783

  With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
