Privacy Policy

Updated 6 October 2026 · Synergy Power Inc

In short. We ask for a Google or Apple account so we know who you are, and we keep your conversations on our servers so they can be delivered to every phone you sign in on. We do not sell data, we do not show ads, and we do not build a profile of you.

Who is responsible for your data

The Meow Messenger app and service are operated by Synergy Power Inc. You can write to us at ceo@synergygrowing.online. You do not need us to delete your account — that is a button in the app, and it is described below.

What we receive when you sign in

You sign in with Google or with Apple. From Google we receive your email address, your name and a link to your avatar — and nothing beyond that. From Apple we receive an account identifier and, the first time only, your name and email address. Your password never reaches us in either case.

If you choose Hide My Email when signing in with Apple, what we store is the relay address Apple gives us. We never see your real one — and because that address belongs to Apple rather than to you, we do not use it to match you with an account you may already have here.

What you add yourself

  • A username — this is how people find you. It is unique and visible to others.
  • A phone number — optional. You can leave it out entirely.

People find each other by username, email address or phone number. Email and phone lookups run against cryptographic fingerprints rather than the values themselves, and only on an exact match, so that search cannot be turned into a way of enumerating other people’s contacts. The address and the number themselves are still stored in your profile.

Messages

The text of your messages, along with emoji reactions and requests, is stored on our servers for as long as your account exists. That stored copy is what rebuilds your conversations on a new phone or after a reinstall, so we do not delete it on a timer. The way to have it removed is to delete your account from inside the app (see below).

Voice notes and photos work differently. Their bytes are deleted from the server as soon as every recipient confirms that they have been saved; if a recipient has a linked computer, a copy may be kept for up to 7 days after the phone’s confirmation so that the computer receives it too; in any case no longer than 30 days. What remains in the conversation afterwards is the record of the message itself — for example “voice note, 0:07”.

Your messages are protected in transit (HTTPS). They are stored on our servers in a form that we are technically able to read: there is no end-to-end encryption today. We would rather say that plainly than hide it behind the word “secure”.

Calls

Audio and video calls run directly between devices whenever possible. Our server takes part in setting up the connection; it receives neither the audio nor the video, nor any recording of either. We do not record calls. When a direct path between two devices cannot be established, the call is carried through a relay server of ours, which passes the encrypted stream along without being able to read it.

So that a conversation starts the moment the call is answered, the connection is prepared while the phone is still ringing. During that time both devices talk only to our relay — even if the call is never answered — and neither learns the other’s network address. No audio travels in either direction before the answer. The first seconds of the conversation go through the relay, and the call then moves to a direct path if there is one.

To make calls work better, the app keeps a technical log of them and may send it to us — either by itself after a call, or when we ask for it while investigating a complaint about call quality. The log contains technical facts only: link quality, packet loss and latency, the phone model and system version, the steps of setting the call up and their timing, who called whom and how the call ended.

What the log does not and cannot contain: no audio, no video, no recording of a conversation, no transcript, no message text, no file names, no content of any kind. We send only what describes how the connection behaved, never what you said or wrote. Logs are kept for no longer than 30 days and are deleted along with your account.

We keep a technical record of each call for up to 30 days: who called whom, when, how long the conversation lasted and how it ended. It exists for exactly one purpose — working out why a call drops or never arrives. The connection-setup data (including the network addresses of the devices) is erased within 15 minutes of the call ending. None of this contains audio or video.

Reactions: front-camera recordings

A message in a one-to-one chat can carry a request for a reaction: the author — whoever sent the message and asked — asks the recipient, the person it was sent to, to record with the front camera how they watch it. These are not the emoji reactions mentioned above. Requests are accepted only in one-to-one chats (not groups), only where the recipient has already written themselves, and only between adults: reactions are for people aged 18 and over.

Legal basis. A reaction is the recipient’s own message, and they start sending it themselves by tapping “Start recording”. So we process the recording to perform our contract with you — delivering your message — and not on the basis of consent. The sheet shown before recording is not a request for consent but a disclosure: it appears before every recording and says plainly that the recording will be sent by itself.

What is recorded. Video from the front camera and sound: you and everything around you, including people near you. The sound of the message itself, while it plays from the speaker, may end up in the recording (with headphones, it does not). The microphone is optional: if you do not allow it, the recording is made without sound, and the author sees a “no sound” mark on the reaction. The camera turns on when you tap “Record a reaction”: you see yourself in the frame, but nothing is being recorded. Recording and the microphone start only after “Start recording” and a 3, 2, 1 countdown.

How long. While the message is open: the length of the content plus 1.5 seconds, but no longer than 5 minutes; for a photo or text, 15 seconds. For a particular message, the sheet states the length before recording begins.

A reaction sends itself. Once you tap “Start recording”, the reaction will reach the author — when you tap “Finish”, when the content ends, or when something interrupts it: you switch to another app, a call comes in, the screen locks, the system takes the camera away, or storage runs out. Recording does not continue in the background: leaving the app ends it. If the app is closed in the middle of a recording, the next launch within a day sends whatever the phone managed to save, and after that the recording is erased and the author sees that the reaction did not arrive. The phone does not always manage: on Android, if the app is swiped away from the list of running apps, the system often cuts it off before the file is finished — the reaction is then lost, and the author also sees that it did not arrive. You cannot preview a recording before it is sent, cancel it or re-record it; you can delete a reaction once it has been sent (see below). Before “Start recording” and during the countdown you can decline at no cost: nothing is recorded or sent, and the author is not told.

The face check. After you tap “Start recording”, while the countdown runs, the phone checks one thing: whether there is a face in the frame. The check is done by the phone’s own system, on the phone itself, and the app receives only the answer: “yes”, “no” or “could not tell”. That answer is not stored, does not appear in logs and is not sent anywhere. We do not identify who it is, we do not build a template or faceprint, we do not compare faces with one another, and we infer neither emotions nor age. The check switches off as soon as recording starts; if no face is found you can start without one. We do not analyse the recording itself in any way — not by face, not by voice — and we do not transcribe it or pass it to artificial intelligence systems.

Who receives it, and what cannot be done with it. One person — the author of the message. The app does not allow forwarding a reaction, saving it, copying it or transcribing it — neither for the author nor for the recipient. We cannot protect a reaction from someone filming the author’s screen with another phone: such a copy cannot be deleted, and we do not promise otherwise.

What the curtain does. Until the recipient decides, the app hides the content of a message that carries a request: only the name, the kind of content and its length are visible. The notification does not show the content either. But this is a rule of the interface, not encryption: the content already sits on the recipient’s phone and in that phone’s backup, and we do not claim it cannot be reached by any route other than the app.

What the author sees. That the recipient asks to view it without a reaction; that the message is open — the mark is set when the recipient starts recording — and that the reaction is on its way; the reaction itself (face, sound) and the “no sound” mark; that the reaction was deleted; that it did not arrive. The author does not see whether a face is in the frame, or whether the recipient is watching the message right now.

“Ask to view without a reaction” and the 24 hours. Instead of recording, the recipient can ask the author to show the message without a reaction — no camera or microphone is needed for that. The author answers “Show” (the message opens) or “Reaction only”; if the author stays silent for 24 hours, that counts as “reaction only”. The recipient then has another 24 hours to record a reaction. When they run out, the rule set on the server applies: the message either becomes unavailable to the recipient (its content is erased from the recipient’s phone) or opens; which one applies is shown on the message’s tile. While the recipient has not decided, a request waits with no time limit.

The switch. You can stop accepting reaction requests — from everyone or from one person. New requests then arrive as ordinary messages, and the author sees only “does not accept requests” — one line, without a reason. Requests already waiting turn into “a request to view without a reaction”: the author decides, and the message does not open by itself.

Age. Reactions are for adults, aged 18 and over; the app itself is for 13 and over. To ask for or accept reactions, the app asks one neutral question, once: “Year of birth”. This is self-reported; we do not verify it against documents. A person counts as an adult if their year of birth guarantees they have reached 18. We do not store the year itself — only a flag, “adult”, “no” or “unknown”, and where the answer came from. The answer cannot be changed in the app.

How long it lives. On the server the bytes are deleted as soon as the author’s receipt is confirmed, and in any case no longer than 7 days — shorter than for other attachments. Backups of our infrastructure are kept for their standard periods, so something deleted from the server may remain in them for some time. On devices a reaction is kept for no longer than 30 days; it is not included in a phone backup. Records of requests and reactions — who, when, for which message, “shown”, “opened”, “deleted”, “did not arrive”, including the time recording started, the version of the sheet’s text and the identifier of the device on which recording started (the consent log) — are kept like messages themselves: after your account is deleted they stay in the conversation for your correspondents, but without your profile (below). The reason a request was dropped when it was sent (including because of the age answer) is kept for 7 days.

How to delete it. A sent reaction can be deleted “for both” — on the “Reaction is being sent” sheet and in the menu of your own reaction. It is erased from the server at once, and from the author’s phone when that phone next connects; while a reaction is still being sent, deleting it cancels the sending. The author keeps a mark “Opened · reaction deleted”, and the message closes for you: a reaction cannot be recorded again. If the author deletes their message, the reaction goes with it. Deleting your account also erases your reactions — including those at your correspondents (below).

Reports. You can report a reaction request or a reaction itself from the message menu, and on a phone also block the author without opening the message. A report carries the location of the message in the conversation; the app does not attach the recording itself to a report.

People who appear in a recording. If you are not a Meow Messenger user but appear in someone else’s reaction, write to ceo@synergygrowing.online with a link to the conversation or a description of where and when it happened. A bystander has no identifiers by which a recording can be found right away, so we find it together with the participants of the conversation and remove it within 48 hours after the place of the recording has been established.

Camera and microphone

The app asks for camera and microphone access and uses them only when you started something yourself: the microphone in calls, while recording a voice note and while recording a reaction; the camera in video calls, when taking a photo, when recording a video-message circle and when recording a reaction (see above). Neither the camera nor the microphone ever turns on by itself, in the background, or without a visible indicator on screen: while a reaction is being recorded, a red dot, the addressee’s name and a timer stay on screen, and they cannot be hidden.

Notifications

To get a notification to your phone we pass Apple or Google a device identifier and a minimal payload — at most the sender’s name. The text of the message is not sent to them; the app fetches it on your phone.

Who we share data with

Only with the services we cannot run without:

  • cloud hosting and the database where your messages live;
  • the Apple and Google push notification services — they receive a device identifier and at most a sender’s name;
  • OpenAI — only when you start it yourself: transcribing a voice note on your tap (the recording goes to Whisper), drawing a portrait from your photo, and the support cat’s replies. Neither your conversations as a whole nor reaction recordings are ever sent there.

We do not sell or hand data to advertisers, data brokers or analytics networks — there are none in the app.

Where data is processed

Data is processed in the United States: that is where the cloud hosting and the database the service runs on are, along with the services listed above. If you use Meow Messenger from another country, your data is transferred to the United States and processed there.

How long we keep things

  • Profile (email, name, avatar link, username, phone number if you added one) — for as long as your account exists.
  • Message text, emoji reactions, requests — for as long as your account exists; there is no automatic deletion.
  • Voice notes and photos — until every recipient confirms receipt (with a linked computer, up to 7 days after the phone’s confirmation), and in any case no longer than 30 days.
  • Device records for notifications — until you sign out or the device stops being used.
  • Reactions (front-camera video and sound) — on the server until receipt is confirmed, and in any case no longer than 7 days (infrastructure backups — for their standard periods); on devices, no longer than 30 days; not included in a phone backup.
  • Metadata of requests and reactions (who asked, when, the answers, the “opened”, “deleted” and “did not arrive” marks, the time recording started, the identifier of the device it started on) — like messages: they stay in the conversation after the account is deleted, without your profile. The reason a request was dropped when sent — 7 days. The age flag and the settings for accepting requests — until the account is deleted.
  • Technical call logs — no longer than 30 days. They contain no conversation or message content.

Children

The service is not intended for children under 13. Reactions are for people aged 18 and over only (see above). Our approach to child safety is set out in the Terms of Use.

Your rights and deleting your account

You can delete your account from inside the app: Profile → Delete account. It asks twice, and the second question is not a formality — after it there is no undo and no way for us to bring the account back.

What deletion does: your profile is wiped — name, username, email address, phone number, avatar — the account stops existing as a way to sign in, and the email address and username become free for someone else to use. You leave every conversation you were in. All your reactions are erased — at your correspondents too: both the recording and the bytes on the server (on a correspondent’s phone, when it next connects). Waiting reaction requests are closed, and the age flag and the request settings are erased. The records of requests and reactions (who, when, the time recording started, the device identifier in the consent log) stay in the conversation like ordinary messages — without your profile.

What deletion does not do, and we would rather say it plainly: the ordinary messages you already sent stay in the chats of the people who received them. They are their conversations too, and we cannot rewrite someone else’s copy of a conversation without taking their messages away as well. What disappears from those chats is you — the messages are no longer attached to a person anyone can open, write to or find. Reactions are the one exception: we do not leave a recording of your face and voice with others.

You can also ask for a copy of the data we hold about you, or ask us to correct it, by writing to ceo@synergygrowing.online. Signing out on your phone deletes nothing — your messages come back the next time you sign in.

Changes

If this policy changes, we will update the date at the top of the page.
