Privacy Policy
Last updated: 2026-09-11
The short version
Pier moves data between two devices you own — your Android phone and your Mac — over your own local network. We do not run servers that your data passes through. We do not have accounts. We cannot see your messages, calls, contacts, files, or notifications, because there is nowhere for us to see them.
Who we are
Pier is developed by CLV Technologies, —.
Contact: privacy@getpier.app.
What Pier does with your data
The Pier Android app reads data from your phone only when you have granted the matching Android permission, and only to send it to a Mac you have explicitly paired with. The data types involved are:
| Data | Why Pier touches it | Where it goes |
|---|---|---|
| SMS messages | So you can read and answer texts on your paired Mac | Directly to your paired Mac over your local network |
| Contact names and photos | So a thread or an incoming call shows a name instead of a number | Directly to your paired Mac; only for numbers already involved in a conversation or call |
| Call log and call state | So your Mac can show recent calls and who is calling right now | Directly to your paired Mac |
| Files and photos you browse | So you can open and copy phone files from your Mac | Directly to your paired Mac, only for files you request |
| Notifications | So notifications appear on your Mac and you can reply or dismiss them | Directly to your paired Mac |
| Clipboard text | So copy-and-paste works across the two devices | Directly to your paired Mac |
| Battery, signal, device name | So your Mac can show your phone’s status | Directly to your paired Mac |
None of this is uploaded to Pier or to any third party. There is no Pier server in the path. There is no analytics SDK, no advertising SDK, no crash reporter that receives your content, and no account system.
How the connection works
Your phone finds your Mac on your local network and connects directly to it over TCP. The connection is encrypted with TLS 1.3, and the two devices pin each other’s certificates at pairing time — so after the first pairing, neither device will talk to an impostor. Pairing requires you to confirm a six-digit code shown on both screens.
Pier does not work over the internet. If your phone and Mac are not on the same network, Pier simply does not connect.
What we collect
Nothing in the app. Pier has no in-app telemetry, no analytics, and no account.
Nothing on this website either. getpier.app loads no analytics script and sets no cookies, and opening a page here sends nothing to anyone but the server that served it — open your browser’s network tab and look. We do intend to count visits one day, with a cookieless tool that needs no consent banner; until that is switched on the script is not on the site at all, rather than sitting here doing nothing. When we switch it on, this paragraph changes and nothing else does.
Two exceptions, both about running the business and neither about your content:
- Update checks. The Mac app asks getpier.app/updates/appcast.xml once a day whether a newer version exists. That request carries what any web request carries — an IP address and the app version — and nothing else; Sparkle’s optional “system profile” reporting is switched off in our build. You can turn automatic checks off in the app. The Android app never checks for updates itself; Google Play does that.
- Buying a licence. If you buy Pier Pro, our merchant of record (Lemon Squeezy) processes the payment and holds your name, email and billing country under its own privacy policy. We store your order number, name, email and issued licence key so we can re-send the key and honour refunds. We never see your card number. The free app asks for none of this.
If you email us for support, we obviously have your email and whatever you tell us. We keep support email only as long as needed to answer it.
Permissions Pier asks for, and why
Pier asks for each permission at the moment you first use the feature that needs it, never up front. You can decline any of them; the corresponding feature turns off and the rest of Pier keeps working.
- SMS (read, receive, send) — to mirror your texts to your Mac and send the ones you type there. Pier does not become your default SMS app; your normal messaging app is untouched.
- Contacts (read) — to show names and photos instead of raw numbers.
- Phone and call log (read phone state, read call log, place calls, answer calls) — to show who is calling, list recent calls, and let you answer, decline, or place a call from your Mac. Pier never records or transmits call audio.
- All files access — to let you browse and copy your phone’s files from your Mac. Pier reads a file only when your Mac asks for that specific file.
- Notification access — to mirror notifications to your Mac and send your replies and dismissals back.
- Foreground service / connected device — to keep the connection to your Mac alive while you use it. Android shows a permanent notification while this is running.
- Companion device pairing — Android’s official mechanism for registering that your phone is paired with a companion device, which is what permits Pier to keep working in the background. It is the same framework a smartwatch uses.
- Change Wi-Fi multicast state — to let your phone hear your Mac announcing itself on your local network, which is how the two find each other without you typing an address.
- Internet and network state — to open the direct connection to your Mac on your local network. Despite the name, Android requires this permission for any network socket, including a purely local one. Pier contacts no internet host.
Pier deliberately does not ask for location, microphone, camera, calendar, or body-sensor access, and does not ask to become your default SMS app.
Children
Pier is not directed at children and we do not knowingly collect anything from anyone, including children.
Your control and your data
- Unpair to delete. Unpairing deletes the pairing and the pinned certificate on both devices, so neither will talk to the other again. The copy of your messages and call history shown on the Mac is held only in memory while Pier is running, and is gone as soon as you quit it. There is no server copy to request or erase, because there never was one.
- Uninstall removes everything Pier stored on the phone.
- Revoke any permission in Android Settings at any time; Pier stops using it immediately and tells your Mac that capability is gone.
- Because we hold no personal data beyond a purchase record, a GDPR/CCPA access or deletion request has almost nothing to return — but write to us and we will confirm that in writing, and delete your order record on request.
Changes
If this policy changes we will update this page and the date at the top. If a change ever means data would leave your devices, we will say so prominently in the app before it happens.
