# Supporter badges
A supporter badge, bought to support SimpleX Chat, is shown next to your name on
your chat profile. With a badge, you can send larger files, from 2 to 5 GB, that
stay available for 7 to 21 days.
A badge is added to one chat profile. It is shown to your contacts, and in the
groups and channels where you use this profile. It is not shown with an
incognito profile.
## Badge types
| Badge | Benefits |
|---|---|
| **Supporter** | Files up to 2 GB, stored for 7 days. |
| **Legend** | Files up to 5 GB, stored for 21 days. |
Without a badge, you can send files up to 1 GB. The app of the person who
receives your file checks your badge before it accepts a larger file.
In incognito chats, you can send files up to 1 GB.
## Where the app offers a badge
- **Settings**, then **Support SimpleX**. With a badge, this row is **Your
badge** or **Your legend badge**.
- The **Support SimpleX** banner in the chat list, shown when you have more than
3 chats and no badge. After you tap it once, you can dismiss it.
- The **Large file!** alert, when you have no badge and choose a file larger
than 1 GB and up to 5 GB, outside incognito chats. It has the button **Support
SimpleX**.
- The alert that opens when you tap another person's supporter or legend badge,
when you have no badge yourself.
On the **Support SimpleX** screen are **How badges protect your privacy** and
the ways to get a badge on your platform.
## Get a badge
| iOS | Android from Google Play | Android from F-Droid or GitHub, and desktop |
|---|---|---|
| **Choose your badge**: the badge page in your browser. **Redeem badge code**: a badge from a code. | **Choose your badge**: a purchase in the app with Google Play. **Restore purchases**: "Moves a paid badge to this profile." **Redeem badge code**: a badge from a code. In the United States, **Buy in browser** is offered as well, and **Redeem badge code** is on the **Choose your badge** screen. | **Buy in browser**: the badge page in your browser. **Redeem badge code**: a badge from a code. |
### Buy on the badge page
Tap **Choose your badge** (iOS) or **Buy in browser** to open the badge page,
badges.simplex.chat. On the page, choose a **Supporter** or **Legend** badge and
the number of months, and pay by card, Bitcoin or Monero.
- When the app is registered to open links from the page, the page shows
**Return to SimpleX** after the payment. Tap it to open the app, which asks
**Add badge to your profile?** and names the profile. Tap **Add badge**. Tap
**Show code** on the page to see the badge code.
- Otherwise, the page shows the badge code, **Copy code**, and a QR code to scan
with your phone. The code is saved only in that browser. Redeem it as
described below.
The iOS and Android apps are registered to open these links. When the desktop
app is not registered to open them, it opens **Redeem code** next to the
browser.
A profile has one badge at a time. If it already has a badge, you can add the
new badge to another profile, or to this profile after the current badge ends.
A badge bought on the badge page is not renewed. It ends when the prepaid months
run out.
### Buy in the app with Google Play
In the Android app from Google Play:
1. Open **Settings**, then **Support SimpleX**, and tap **Choose your badge**.
2. Choose **Supporter** or **Legend**, and tap **Continue**.
3. Choose **1 month**, **Monthly** or **Annual**, and tap **Continue**.
**Monthly** and **Annual** are subscriptions that renew until you cancel
them.
4. Check your order and tap **Pay**. Complete the payment in Google Play.
While the badge is being added, the app shows **Issuing your badge**. When the
payment needs approval, the app shows **Waiting for approval**, and nothing is
charged until it is approved.
### Redeem a badge code
1. Open **Settings**, then **Support SimpleX**, and tap **Redeem badge code**.
2. Tap **Paste**, type the code, or scan its QR code. Badge codes look like
SB-XXXXX-XXXXX-XXXXX-XXXXX. Scanning is available on iOS and Android.

The badge is added to your current profile.

The app updates the badge every month while paid months remain, with no action
from you.
## Badge alerts
The chat list shows a banner about your badge in these cases. Tap the banner to
open **Your badge**, or **Support SimpleX** when the badge has ended.

| **Your badge renews soon** | 3 days before an annual subscription is renewed. |
To close a banner, tap its close button and choose **Remind me later**, to see
it again after one day, or **Dismiss**.
## How badges protect your privacy
A badge is an anonymous credential stored in your profile on your device.
SimpleX Chat has no user accounts, so the badge is not attached to an account.
The credential itself is not sent to anyone.
To show a contact or a server that you have a badge, the app generates a new
proof each time. A proof contains the badge type and the expiry date, rounded to
a week. Two proofs cannot be linked to each other or to the purchase.
The app sends a new proof with your profile each time it sends the profile: to a
new contact, in your SimpleX address and 1-time links, to the groups and
channels you join, to your contacts when a badge is added, and with your profile
updates. A file larger than 1 GB is sent with a proof as well.
The expiry date is the same for all badges whose paid month ends in the same
week: the end of the following Monday. The apps of other people accept a badge
for 7 days after this date. After that, the badge is shown dimmed, and one month
later it is no longer shown.
The design is described in the [supporter badges
whitepaper](https://simplex.chat/docs/protocol/badges-overview.md).
## Badges of other people
A badge is shown after the person's name. Tap it in the contact info, in the
member info, or in the profile shown at the start of the chat to see what it
means:
- "[name] supports SimpleX Chat." for a supporter or legend badge;
- "[name] supported SimpleX Chat. The badge expired on [date]." for a recently
expired badge.
When the app cannot verify a badge, it shows a warning sign in its place.
Tapping it shows **Unverified badge**, or **Badge cannot be verified** when the
badge is signed with a key that this version of the app does not recognize.
