## What is Sindiy?

"Sindiy" is an application for managing passwords. It is created focusing on the basic minimum functions of saving passwords, sorting, and managing passwords.(There is no dangerous function like copying the password to the cloud.)
No troublesome procedures such as user registration are necessary, so you can use it immediately after installation.

Since all saved passwords are encrypted, it is possible to reduce the possibility of password leakage when using iCloud's backup function or even in the event of your iPhone(iPad) loss.

You can select "None", "TouchID", "Master Password" for authentication at application startup."Master Password" provides the most robust security environment, but you must enter the password each time the application is launched. On the other hand, "None" improves convenience but weakens security.
You can select the optimum method according to your own scene.

## Key features

- Password saving
- Password sorting
- Encrypted storage
- No cloud sync
- Multiple authentication options
- Immediate use after install

### 4/5 — 使いやすくて良いけど……！

*2021-05-06, version 2.1.1*

画像貼った時に新しく作るのでは無くて(フォルダを)
上書き保存にして欲しい……

### 4/5 — 悪くない

*2021-04-29, version 2.1.1*

たしかにアップデートで使いづらくなりましたが、使えないほどではありません。機能も必要最低限って感じです。ですがパスワード管理アプリとしての役割はちゃんと果たしていて、今まで特に問題はありませんでした。無料である事を考慮すれば十分だと思います。

### 2/5 — 使いずらい

*2020-12-23, version 2.0.1*

アップデートして使いづらくなった。
あと、データを更新しても、アプリを落としたら更新したはずのところが更新されてない。

### 1/5 — 機能が貧弱過ぎ

*2020-02-28, version 1.2.1*

touch IDやパスワードで解除するメモリスト。パスワード管理ではない。利用者がパスワード管理を頑張るだけ。下記を理由にオススメしない。

(１)パスワードを生成してくれない

折角アプリで管理してるんだから、人が簡単に覚えられないパスワードを扱いたいが、生成機能はないので他アプリで生成するしかない。

(２)パスワードの強度を判定しない

パスワードは手入力しかないが、その強弱は他アプリで調べるしかない。

(３)自動では呼び出せない

webでパスワードが必要な場面が来ても、UXに乗らない。

(４)アカウントの使用頻度を教えてくれない

長く使わないサイトの退会などのUXに乗らない。

このアプリを使うことによって、パスワード管理しようとすれば出来るが、危機管理能力を改善する事は出来ない。

紙メモがiPhoneメモに変わるだけ。覚えられるパスワードが使い回されるだけ。古いアカウントは放置され、セキュリティ危機管理能力とは無縁のアプリ。

### 1/5 — 個人情報消えた

*2019-10-06, version 1.2.1*

青い画面から変わらず。

### 1/5 — 前まで良かった

*2019-09-15, version 1.2.1*

アプリ開いても青い画面から動いてくれなくなった
