Privacy Policy

How the Sender Extreme app handles your information — in plain words.

Effective date: 7 October 2026 · Applies to Sender Extreme for Android (website and Google Play versions), Windows, iPhone/iPad (web app) and the web.

Who we are What we collect How we use it Who it is shared with Phone contacts Reports & safety Permissions How long we keep it Security Your choices Delete your account Children Changes Contact

We do not sell, rent or trade your personal information.
There are no ads, no advertising trackers and no analytics tools in the app.
Secret chats are end-to-end encrypted: not even our server can read them.
Your phone contacts are used only when you ask, are only compared, and are never stored.

1. Who we are

Sender Extreme is a free messaging app made and run by Christopher Marlowe Suarez Macalino (“the developer”, “we”), Poipet, Cambodia. For any privacy question or request, write to christophermarl168@gmail.com.

2. What information we collect

Information	Why
Account details: your name, e-mail address, password (stored only in scrambled/hashed form), and optionally your phone number, @username, profile photo and bio	To create your account, sign you in, and let people find and recognise you
Your private number: a random number the app gives your account	So people can contact you without knowing your phone number
Messages and what you send: text, photos, videos, voice and video messages, files, polls, stickers, reactions and locations you choose to send, in normal chats, groups and channels	To deliver them and keep them in sync on all your devices
Stories and live streams you post, and who viewed your stories	To show them to the people you chose
Calls: who called whom, when, how long, and whether it was answered (not the sound or video)	To connect calls and show your call history
Your contacts list inside Sender Extreme, blocked people, folders and settings	To run those features
Online status and “last seen” time	To show friends when you are online, if your privacy settings allow it
Device and session details: device name (for example “Android app · Galaxy A15”), platform, app version, when a device signed in and was last active	To list your signed-in devices in Settings → Devices & sessions, so you can sign them out
Notification tokens: a random code for each of your devices (and, in the Google Play version, Google’s push token)	To send you new-message and call notifications when the app is closed
Donation records (only if you report a donation): method, amount, reference number, the name and country you enter, and a note	So the developer can confirm the donation and thank you
Reports you send: the reason, your note, and — when you report a message — that message and up to 5 messages before it	So the Sender Extreme team can check the report and keep the app safe (see section 6)
Safety records: warnings, suspensions and bans of an account, and why	To enforce the rules and prevent abuse
Phone contacts (Android, only when you ask — see section 5)	To show which people from your phone use Sender Extreme. Not stored.

We do not collect your location in the background, your SMS messages, your call log, advertising IDs, or browsing history. Messages in secret chats are encrypted on your device; the server only stores encrypted data it cannot read.

3. How we use your information

To provide the app: accounts, messaging, calls, stories, live streams, notifications, and syncing between your devices.
To keep the app safe: checking reports, warning, suspending or banning accounts that break the rules, preventing abuse and spam, and letting you see and terminate sessions you don’t recognise.
To answer you when you contact the developer.

We do not use your information for advertising or profiling, and we do not sell it.

Your information is shared only with the people you choose to communicate with, and with these service providers that run parts of the app for us:

Service	What it does	What it receives
Supabase	Database, file storage, sign-in and live connection (the app’s server)	Your account, messages (normal chats), files, and the other information in section 2
Netlify	Hosts the website and app downloads/updates	Standard web request data (such as IP address) when you open the website or the app downloads an update
Google Firebase Cloud Messaging (Google Play version only)	Wakes your phone for notifications	Your phone’s push token and an encrypted notification that only your phone can read
Google STUN servers	Help two phones connect for a call	Your IP address during call setup (calls themselves go directly between the two devices, encrypted)
MyMemory (translated.net)	Translation	Only the text you tap “Translate” on
Your phone’s speech service (for example Google)	Voice typing	Your voice, only while you use voice typing
OpenStreetMap	Maps	A location, only when you open one on the map

During a call, the two devices connect directly, so the person you call can technically see your device’s IP address. We may also disclose information if the law requires it, or to protect users from serious harm.

5. Phone contacts (Android)

In Contacts → Find friends from my phone contacts, the Android app can show which people saved in your phone use Sender Extreme. This happens only after you tap it, read an explanation, and allow Android’s Contacts permission.

The app reads the names and phone numbers in your phone’s contacts.
Only the phone numbers are sent, over an encrypted connection, to be compared with the phone numbers of Sender Extreme accounts. The names stay on your phone.
The numbers are not saved on the server, not added to anyone’s account, and not shared with anyone. They are used for the comparison only and then discarded.
People who turned off “Find me by phone number” are never shown.
You can stop at any time with Stop using my phone contacts, and remove the permission in Android Settings → Apps → Sender Extreme → Permissions.

6. Reports and safety

You can report a person (their profile → ••• → Report) or a message (press and hold it → Report), and you can block anyone.

A report sends the reason you chose, your optional note, and — for a message — that message and up to 5 messages before it from the same chat to the Sender Extreme team. In a secret chat the server cannot read messages, so your phone sends their readable text; you agree to this when you send the report.
The person you report is not told who reported them.
The team may dismiss the report, send the account an official warning, suspend it for 7 days (it cannot send messages, post stories or call), or ban it (it is signed out everywhere and cannot be used again). The person sees the action and the reason. These decisions are recorded.
If your account was suspended or banned by mistake, write to christophermarl168@gmail.com from your account’s e-mail address.

7. Device permissions

The app asks for camera, microphone, notifications, photos/videos, contacts and other permissions only for the features that need them. The full list and the reason for each is on the declaration page. You can refuse or remove any permission; only the feature that needs it stops working.

8. How long we keep your information

Messages and files: until you or the other person deletes them, or until the chat’s auto-delete timer removes them.
Stories: 24 hours (unless you save them yourself).
Sign-in QR codes: removed within 10 minutes.
Sessions: until you terminate them, or automatically after the period you choose in Devices & sessions.
Phone contacts: not kept at all.
Reports and safety records: as long as needed to handle the report and prevent further abuse. You can ask us to delete reports you sent.
Your account: until you delete it. When it is deleted, your profile, contacts, settings, stories and sessions are deleted. Messages you sent in groups and to other people may remain visible to them, shown without your profile.

9. Security

All connections use HTTPS/TLS encryption. The database only lets each user read what they are allowed to see. Secret chats are end-to-end encrypted, Google Play notifications are encrypted for your phone only, and you can protect the app with a PIN or fingerprint lock. No system is perfectly secure, but we work to protect your information.

10. Your choices and rights

Edit your profile, phone number and photo at any time in Settings → My account.
Choose who sees your phone number, last seen and online status, who can call you, and whether people can find you by phone or e-mail (Settings → Privacy & security).
Delete messages, chats and stories; turn notifications off; sign out devices.
Ask for a copy of your information, or ask us to correct or delete it, by writing to christophermarl168@gmail.com. We reply within 30 days.

11. Delete your account

You can delete your Sender Extreme account and its data at any time:

In the app: Settings → Delete my account, type your password and confirm. Your account is locked at once (signed out everywhere) and is deleted for good after 7 days, together with your profile, contacts, settings, stories, devices and the photos, videos, voice messages and files you uploaded. Changed your mind? Sign in again within the 7 days and choose Keep my account. Or
By e-mail: send a message to christophermarl168@gmail.com with the subject “Delete my Sender Extreme account”, from the e-mail address of your account, including your @username or private number.

For e-mail requests, your account and the data described in section 8 are deleted within 30 days. Backups are cleared within a further 30 days. You don’t need to have the app installed to ask.

Delete some of your data, and keep your account

Messages: press and hold a message → Delete. Delete for everyone (your own messages) erases its text from the server at once and removes its photos and files from the chat; Only for me hides it from you. Press and hold a chat → Delete chat to remove it from your list.
Stories: open your story → Delete. Stories are deleted by themselves after 24 hours.
Profile details: Settings → My account → remove your photo, bio, @username or phone number.
Phone contacts: Contacts → Stop using my phone contacts (they are never stored).
Anything else (for example donation records, or the stored photo and video files of messages you deleted): e-mail christophermarl168@gmail.com from your account’s e-mail address saying what to delete. It is deleted within 30 days.

12. Children

Sender Extreme is not meant for children under 13, and we do not knowingly collect information from them. If you believe a child under 13 has an account, contact us and we will delete it.

13. Changes to this policy

If this policy changes, the new version is posted on this page with a new effective date, and important changes are announced in the app.
