## Session Description
Session is a new breed of private messenger, built on a unique network of user-operated servers spread all over the world. With no central servers, Session can’t leak or sell your data. And with Session’s private routing protocols, your messages are completely safe. No trackers, no leaks — send messages, not metadata.

• Fully private account creation: No phone number or email needed to create an Account ID

• Decentralized server network: No data breaches, no central point of failure

• No metadata logging: Session doesn't store, track, or log your messaging metadata

• IP address protection: Device IP addresses are never exposed to the person you're talking to or the servers holding your data

• Closed groups: Private, end-to-end encrypted group chats for up to 100 people

• Secure attachments: Share voice snippets, photos, and files with Session's secure encryption and privacy protections

• Free and open-source: Don’t take our word for it — check Session's code yourself

Session is free as in free speech and free as in free of ads and trackers. It is stewarded by the Session Foundation, a Swiss-based foundation dedicated to advancing digital rights and innovation. Take back your online privacy today — download Session.

## Session Reviews in Japan

### **--- "通話が不安定（※追記あり）"
まだβ版の機能なので仕方ないのですが通話機能が不安定なのが残念です。 繋がりにくい、繋がっても再接続が多い、音質が若干悪いと思います。

使用端末はiPhone SE2とiPad Air M2で、併用しているアプリはAppleのプライベートリレーとー広告ブロッカーのAdGuardです。
プライベートリレーとAdGuardをON/OFFしても繋がりません。

今後、通話機能の改善に期待します。
その他にはSession公式webサイトからできる寄付について、支払い方法にApple Payを加えてもらえると嬉しいです。
-- Mizuki@JP, 2024-10-19

### *---- "時差がひどい"
ひどい時は1ヶ月後にメッセージ受信したり、受信して削除したのにまた同じメッセージが届いた事もあった。
はっきり言って信用できない。
-- paradoxxx369, 2024-10-11

### ***-- "It's easy to use."
Not sure about safety, but thought it was easy to start using.
One area for improvement is that the battery drains quickly.
(I am Japanese, sorry for my poor English.)
-- hdyyyyyyu, 2024-10-10

### ***-- "メッセージが完全に消えない"
ネットワークから削除を選択すれば消えるけど

バグがまだまだ多い

テレグラムの代替するにはもっとシステム改善をしてほしい
-- 成金555, 2024-10-06

### *---- "送信できません"
アップデートしたら送信できなくなりました
-- せちゅんこ, 2024-09-17

### *---- "アドレス帳"
連絡先の登録ができない、一覧がない。
メッセージを消すと連絡先ごと全て消える
-- ランデン444, 2024-09-05

### ****- "セキュリティ最強"
ただ、なぜか自分のプロフィールアイコンを変更しようとすると更新に失敗します。。

運営さんどうにかしてください
-- たじまっくす, 2024-07-10

### *---- "画像送信失敗"
セキュリティ、プライバシーについてはよく考えられています。
しかし画像送信に時間がかかりすぎる。送信成功に20分、受信側での読み込みに20分はいくらなんでもかかり過ぎです。不採用。
-- naoki.k10, 2024-07-05

### ***-- "電池消費以外最高"
自動消滅メッセージ、高度な暗号化と身元を明かさずに登録できるのは最高なのですが、バッテリー消費が半端じゃない。

メリットを全て帳消しにするバッテリー消費。
VPNのようなことをアプリ内でやってるのでそれが問題かもしれないが…
バッテリー問題さえ解決したらお金を出しても購入するくらいいいアプリです
是非改善願います
-- 投票受付中, 2024-07-01

### *---- "使い物にならない"
送信できないし時差が酷い
信頼に関わるし人間関係が破綻してしまう
-- ​─, 2024-06-10

### ****- "session token"
暗号通貨の方も期待大
-- パンチラボーイズ, 2024-04-24

### ***-- "mistranslation in the status message？"
I've noticed a potential mistranslation in the status message of your app, where it should likely say "Sending" or “送信中” but instead says "Sending money" or "送金中". This could lead to confusion among users. Could you please check and correct this?

Best regards
-- _Skit, 2024-03-16

### *---- "リカバリーフレーズ入れて追加しようとしてもできない。"
落ちますよ？
-- ☻なひなつ, 2024-01-09

### ***-- "Can't call"
The messages are great.

However,
This app doesn't allow you to talk on the phone.

Even if an incoming call arrives, tap the call button to hang up.

Please make improvements.
-- TTTvg@a, 2024-01-01

### ***-- "グループ作成について"
グループ作成をした本人しかグループメンバーの削除ができないのでしょうか？

それとグループ作成した本人がグループ参加招待をしないとトークに入れないのを改善できませんか？
-- さかたゆやひまむ, 2023-12-27

### *---- "文字サイズ変更できない"
システム設定を有効にしても文字サイズが
変更されないため文字のデカさが間抜けです。
変更できないのでしょうか。
プライバシーの強さを謳ってますが
文字が大きすぎて背後からのプライバシーは皆無です。
iPhone14pro iOS17.1.1
-- そらとん, 2023-11-12

### ****- "送信できません"
急に送信ができなくなりました。友だちと連絡が取れずに困っています。
-- お野菜戦隊ニンジンマン, 2023-04-11

### ***-- "iPhone10ですが、、、"
パスが表されず、送信も受信もされずに困っています。確認お願いいたします。
-- アップでー太郎, 2023-04-09

### ***** "great app"
I think it's safer than any messaging app!  Even easier to use!

 If I had to mention one point, I would be happy if you could add a function that makes the message disappear after a certain amount of time has passed since the other party has read it.  I hope everyone will use this app.
-- らみぃのーず, 2023-04-06

### ****- "Thank you for paying attention to user feedback"
Update: 
 Issues that mentioned below have been solved in the latest version.
 I’v been using Session since 2021; almost every single update made this app a better one from the origin version . Thanks to the efforts that developers paid to respond user expectations. 
BTW there is a new problem in the latest version. When I try to type a keyword in the search bar on homepage to search something in the chat history, the app just crashes immediately. Please fix it. 

 Almost can’t receive messages instantly while the sender has already sent them. The delay is soooooo long and I don’t know why things like these could happen in an IM app. Also can’t send short videos. BTW the UI is awesome though.
