Crowner Technology Inc. · Richmond, British Columbia

Careful software, made in Canada.

We design, build and run our own apps: a private messenger for families, a record of every time your phone’s microphone or camera is used, and two companions for crypto markets that never hold your money.

What we make

Four apps, described in their own words.

Designed, built and run by Crowner in British Columbia. Each one says plainly what it does, and what it does not.

Private family messenger

Windpost

  • In testing
  • iPhone and Android
  • Adults only

A private messenger for your family and the people close to you: encrypted end to end, kept on your phones rather than our servers, and nobody gets in without an invitation.

  • Encrypted end to end

    Words, photographs, voice, video, documents and calls are sealed on the phone that sends them. The relay that passes everything on holds no key and cannot read a word.

  • No phone number, no strangers

    Your account is a key made on your phone. There is no directory and no search: every contact starts with a code handed over by a person.

  • Families, groups and albums

    Smaller circles inside a family, must-read messages answered with Got it, polls and events, and albums kept at full size on the family’s phones.

  • Calls with up to five people

    Voice and video, phone to phone, through a forwarder that holds no keys — with screen sharing, and effects drawn on your own phone.

  • Help, sent and never taken

    Share where you are once or live for a while, press Help me or hold SOS for two seconds, and your family is told at once. Windpost is not an emergency service.

  • Grandparent mode and documents

    One switch for a few large buttons. Passports and papers sealed in My documents and reminded before they expire; scan, sign and send a PDF.

Soon on theApp Store Soon onGoogle Play

Invited families are testing it now, and it comes to the App Store and Google Play after testing. Free while it is being tested.

Microphone and camera log

Earshot Privacy

  • On Google Play
  • Android 12 and above
  • No account

Earshot Privacy records every time a phone’s microphone or camera is used, keeps that record for months instead of the day Android keeps it, and adds four checks for the room you are in.

  • Every use, with its time and length

    Whether the screen was off and the phone locked at the time, and which ones were your own face unlock, so you are not alarmed by yourself.

  • Right now, and at night

    What is using the microphone or camera right now, how many uses happened at night, and on which nights.

  • Camera search

    A guided search of the places cameras actually get hidden — smoke detectors, chargers, clocks, vents — plus a lens scan for bright reflections and infrared light, through your own camera.

  • Wi-Fi and Bluetooth searches

    Names what answers on the network you are on, including anything streaming video, and finds trackers and devices broadcasting nearby.

  • Save a place

    The next scan in a room you saved tells you what arrived and what left: a rental, a hotel, anywhere you go back to.

  • Everything stays on your phone

    No server, no account, no sign-up, no analytics, no advertising. The app never opens your microphone.

Free, and all four room checks with their full results are free to everyone. Pro is a single payment of US$14.99, not a subscription: alerts that ring, months of history, the night-time pattern in detail, and what changed in a place you saved.

Solana token alerts

RuleFire

  • On Google Play and the App Store
  • Read-only, no keys
  • No account needed

RuleFire watches Solana tokens for you and tells you when your rule fires — with the rule’s own track record beside every alert, so you can see how often it has been right before.

  • Rules become alerts

    Start from a template — volume 3×, VWAP reclaim, RSI recovery, 48-hour breakout — or build your own on Pro. Push notifications, and Telegram if you choose.

  • A track record on every alert

    How many times the rule fired over the last 30 days (90 on Pro). A rule that has not fired enough times shows no number rather than a flattering one.

  • Checks before Buy

    Freeze authority, mint authority, holder concentration, liquidity and sanctions screening, each with its source named. A hard trap removes the Buy button.

  • Handoff, not custody

    Buy opens your own wallet — Phantom, Jupiter Mobile or Solflare — with the token pre-selected. You confirm every trade in the wallet itself.

  • Positions and receipts, read-only

    Add a public address to see what it holds, average entry, profit and loss, and every trade with the fees it paid. Export for Koinly or CoinLedger.

  • A free token checker on the web

    Paste a Solana token address at rulefire.trade and see the traps. No account, and nothing you paste is stored.

RuleFire is not a wallet, not an exchange and not advice. It cannot place, cancel or sign anything, and never holds keys or funds. It watches public data and describes what happened. Whether to trade is yours.

RuleFire checks what can be checked. It cannot see everything, and history is not a prediction. Not financial advice.

Free to start: three saved rules from the templates, one watched address, five alerts a day. Pro is a monthly subscription through the store.

Crypto screener and alerts

DexAlert

  • On Google Play and the App Store
  • Phone and web

Every major coin, one technical read: a multi-chain screener with signals, and a strategy builder that tests your rules against historical data and alerts you when they fire.

  • Blue chips on three chains

    The top coins by market cap on Solana, Ethereum and Base, plus BTC, ETH and the majors — stablecoins, wrapped and RWA tokens filtered out. No memecoins.

  • Eight indicators, three timeframes

    RSI, MACD, EMA 9/21, Bollinger, VWAP, Stoch RSI, ADX and volume, read across 30m, 1h and 4h for every coin.

  • Signals the moment they trigger

    EMA and MACD crosses, Stoch RSI reversals and full trend flips on 1h or 4h, in a live feed — and Signal Copilot beside every chart shows which indicators are green or red.

  • A strategy builder with backtests

    Plain-sentence rules with take-profit, stop, trailing and time exits, tested against historical data: three months on the free plan, up to 24 months on paid plans.

  • Strategy Finder

    Every night the engine tests tens of thousands of rule combinations and keeps only those that survive months of data they were never trained on.

  • Push and Telegram alerts

    Mobile push and Telegram messages when a strategy fires, on every plan, the free one included.

Educational tool — not financial advice. Simulated results are hypothetical.

DexAlert never holds or has access to your funds, keys or exchange accounts, and cannot place orders for you.

A free plan with the full screener, two strategies and alerts; Pro and Platinum add more strategies, longer backtests and more Strategy Finder searches.

How we work

Built to leave things out.

What each app collects, and what it never touches, is written in its own privacy policy. A few of the things they leave out:

What our apps leave out

  • WindpostNo ads, no analytics, no phone number and no contact upload. The relay that carries messages holds no key to them.
  • Earshot PrivacyNo server, no account, no analytics, no advertising. Nothing it records is sent anywhere.
  • RuleFireNo sign-up, no email, and never a wallet key or seed phrase. It cannot move your money, because it never holds anything that could.
  • DexAlertNo access to your funds, private keys or exchange accounts.
  • This siteNo cookies, no analytics, no trackers, and nothing loaded from anyone else.

End to end

Interface, backend services, data pipelines and the infrastructure underneath — designed and operated by the same team.

Limits, in writing

Windpost publishes a list of what it cannot do. RuleFire never calls a token safe. Earshot shows what it checked and what it could not.
