## What is Pyunto?

A place to write how you feel right now, with complete peace of mind.

Pyunto is a diary that belongs to you alone. Whatever happened today, whatever crossed your mind, photos, videos — keep it all however you like, as much as you like.

Write quietly on your own, of course, or start an exchange diary with someone special, or share your days with family and friends in a group diary. Alone, as a pair, or all together. How you enjoy your diary is entirely up to you.

The in-app assistant can gently accompany your words, too. It can help you look back on what you wrote, or quietly tie it together. And because the assistant runs only inside your device, your diary never leaves it.

You don't need an account or an email address to start. The moment you open it, you can already write. Every entry is encrypted and stored securely. Exchange diaries and group diaries are encrypted as well — in transit and in storage.

Why not start with a single line about today?

Here's how you can use it

On your own — for records, memories, and putting your heart in order
As a pair — a couple diary with someone special
All together — a group diary with family and friends
Chat with the in-app assistant (it runs only inside your device)
No account, no email, everything encrypted
You can also create an account if you wish. That lets you use Pyunto across multiple devices and transfer your data.

### 1/5 — Twitterの代わりなら

*2026-08-14*

サブスクが高いですが一人で使うなら無料で問題ないです
AIを入れるとものすごく容量を食います
AIなしで淡々とひとりごとを打つのに使うならいいかもしれません

**Developer response:** レビューをいただきまして、ありがとうございます。
いただきましたご意見を開発チームで共有し、モデルの容量については、改善できるように調査・研究を進めて参ります。
どうぞ、よろしくお願い致します。

### 4/5 — オフラインでは使えない！

*2026-08-04*

全てはサーバーとの通信で成り立つ！
データはサーバー！

サーバーが飛んだら全てのデータが

なくなる！

**Developer response:** レビューいただきまして、ありがとうございます。

このアプリは、最初にローカルにデータを保存したあと、可能な場合にデータを暗号化した上でサーバにもバックアップを保存しています。（保存したユーザおよび、交換日記やグループ日記の相手のみしか閲覧できない暗号化を採用しています）

これにより、サーバに万が一障害などが発生しました場合は、ローカルのデータのみでお使いになれるように、設計はしておりますが、わかりにくい点は、申し訳ありません。今後改善してまいります。

また、この機能により、後からアカウントを作成されたユーザの皆様が、スマホやパソコンなど複数の端末でご利用いただくことが可能になります。

ローカルデータのみでお使いになります場合は、「瞬間日記」など他のアプリもご検討いただけましたら幸いです。（その場合、WiFi経由でバックアップを取れるようにするなどの手段を提供しています）

以上、どうぞ、よろしくお願いいたします

### 5/5 — 子供と交換日記

*2026-07-09*

登録が簡単ですぐ始められました。

LINEをやりたがっている小学生の子供と、その代わりにこのアプリで交換日記をしています。クローズドで安心だし、親子のやりとりが日記として残っていくのが思った以上に楽しいです。画像も送れるので、その日の写真を貼って見せ合ったりしています。

ちょっとした書き留めに、ひとり用の簡単なメモとしても使えて便利です。AI機能もこれから充実していきそうなので期待しています。

**Developer response:** レビューいただきまして、ありがとうございます
ご期待に添えるように、今後も、改善していきます。
小学生のお子様との、大切な日々をより豊かにすることに、Pyuntoが少しでも役立てましたら幸いです。
引き続き、どうぞ、よろしくお願い致します。
