Dengen Shrine – A privacy-focused digital Shinto ritual

Hi HN, I built "Dengen Shrine," a web-based experience of a traditional Japanese Shinto ritual. Key Features: Privacy by Design: Your "Kotodama" (messages/prayers) are never stored in any database. They exist only in the animation and vanish upon completion. No Login Required: You can experience the ritual instantly without an account. Digital Offering: For those who wish to support the project, I’ve integrated a "digital offering" (Osaisen) via Stripe. This is completely optional—you can experience the core ritual for free without any payment. It’s not a donation, but a paid digital…

What it does

In the maker’s words, at launch

Hi HN, I built "Dengen Shrine," a web-based experience of a traditional Japanese Shinto ritual. Key Features: Privacy by Design: Your "Kotodama" (messages/prayers) are never stored in any database. They exist only in the animation and vanish upon completion. No Login Required: You can experience the ritual instantly without an account. Digital Offering: For those who wish to support the project, I’ve integrated a "digital offering" (Osaisen) via Stripe. This is completely optional—you can experience the core ritual for free without any payment. It’s not a donation, but a paid digital experience that unlocks a unique "Completion Message" for supporters. Why I built this: I wanted to explore how ancient traditions like Shinto can be reinterpreted in a digital, ephemeral way. In Shinto, words have spirits (Kotodama), and I felt that the "ephemeral" nature of the web was a perfect fit for this. I’d love to hear your thoughts on the UI/UX and the concept of "ephemeral digital rituals."

    Hi everyone! This is my first HN and I’m very new to the scene. My name is Min from Bangkok. At first, I just want to create a dead man's switch for personal use and for fun. then, I think about information that self destruct like a spy movie. after that, I try to come up with the better version of Privnote or Bitwarden with self-destruct and some kind of censoring or blocking download ability. Somehow, end up with this product. :O Flashpaper is for sending any information that would be burned after reading (with counting down timer like Mission Impossible movie ! or after 24 hrs max if not…

    ToolKuai – Privacy-first, 100% client-side media toolsJan 2026 · toolkuai.com · ▲8

    Hi HN, I’m Linn, the creator of ToolKuai (https://toolkuai.com). Like many of you, I’ve always been wary of "free" online file converters. Most of them are black boxes: you upload your private documents or images to a remote server, and you have no idea where that data ends up or how it’s being used to train models. I wanted to build a suite of tools (Video/Image compressor, OCR, AI Background Remover) that runs entirely in the browser. No files ever leave your machine. The Tech Stack To make this performant enough to rival server-side processing, I leaned heavily into modern…
