MT5er Notifier privacy policy
Last updated November 12, 2026
MT5er Notifier is an app for iPhone, iPad and Android that shows a MetaTrader 5 trading account and, if you add one, a SignalStart signal. I'm Bryan Joseph, an individual developer, and I make MT5er Notifier. This page says what the app keeps on your phone, what it sends, and to whom.
The short version: your broker login and password stay on your phone and go only to your broker's own server. MT5er Notifier has no sign-up, no ads, no analytics and no crash reporting. It sends me something only when you tap "I want this" on the 24/7 alerts card or "Request my broker".
What stays on your phone
- Your broker server, login and password, kept in the phone's secure storage (the iOS Keychain, or Android's Keystore-backed storage). They're stored for this device only, so they aren't synced or included in backups.
- A random device identifier made on first launch. The broker's web terminal asks for one, so MT5er Notifier sends it to your broker when it connects. It isn't sent anywhere else.
- Account history for the charts (equity, balance, drawdown, margin and the times monitoring stopped), your alert rules and your settings. The history file is excluded from iCloud and Google backups.
Removing an account in Settings deletes its password, history and alert rules. Deleting the app deletes the rest. iOS can keep Keychain items after an app is deleted, so when MT5er Notifier is installed again it clears any it finds from the earlier install.
Who MT5er Notifier talks to
Your broker
MT5er Notifier connects to your broker's MetaTrader 5 web-terminal server over an encrypted connection. It sends your login, your password, the device identifier above and requests for account figures, open positions, prices and chart data. It checks the server's certificate against the address your broker publishes. MT5er Notifier can't place, change or close trades or move money. Your broker's privacy policy covers what the broker does with this. None of it is sent to me.
SignalStart, if you add a signal
MT5er Notifier reads the signal's public SignalStart page every 5 minutes while the app is open and monitoring. SignalStart sees your IP address, the page address and an app identifier ("MT5erNotifier" and its version). MT5er Notifier doesn't ask for or store a SignalStart login. SignalStart's own privacy policy applies to those requests.
MT5er Notifier's server
MT5er Notifier has a small backend on Convex, a hosting service. When the app is open it reads two things from it: on/off switches for upcoming features and the list of supported brokers. Those reads include nothing about you or your account. Like any website, the hosting service sees your IP address while the connection is open. I don't store it.
The backend stores something only when you tap one of two buttons:
| You tap | What's stored | Why |
|---|---|---|
| "I want this" on the 24/7 alerts card | A random installation ID the app makes for this purpose, the platform (iOS or Android), the app version and the times you tapped. Not your name, email, broker, login or any account figure. | To count how many installations want alerts that keep working while the app is closed. "Undo" marks the entry as withdrawn. |
| "Request my broker" | The broker server name you entered (for example "ExampleBroker-Live"), the platform and the time. No installation ID. | To decide which brokers to add next. |
Both kinds of entries are deleted automatically 24 months after they last changed. Demo mode ("Try demo data") sends neither.
Expo, for app updates
When it starts, MT5er Notifier asks Expo's update service (EAS Update) whether a newer version of its JavaScript is available. According to Expo, these requests carry the phone's operating system, the app's project ID and a random token, and no device identifiers. Expo's privacy policy applies to them.
Notifications
Alerts are local notifications that the app creates on your phone. MT5er Notifier doesn't use a push notification server. Alert text can include amounts and percentages. Turn on "Hide amounts" in Settings to leave them out. Whether notifications show on the lock screen is set in your phone's settings.
What MT5er Notifier doesn't do
- No accounts with me, no sign-up and no email collection.
- No advertising, analytics or crash-reporting libraries.
- No tracking across other apps or websites, and no advertising identifier.
- I don't sell or share data with anyone.
Children
MT5er Notifier is for adults who hold trading accounts. It isn't directed at children.
Your choices
- Use your broker's read-only investor password. MT5er Notifier recommends it and warns you when the password it was given can trade.
- Remove an account in Settings to delete its password, history and rules.
- Tap "Undo" on the 24/7 alerts card to withdraw your interest.
- The entries on MT5er Notifier's server carry no name, email or account number, so I can't find yours by asking who you are. If you have a question about them, email me.
Changes
If this policy changes, the new version goes on this page with a new date. If a change means MT5er Notifier sends something new, the app update that does it will say so.
