DoSync is an app to control the devices in your home from your phone. It is designed so that your data stays on your phone.
| Data | Where it is stored | Does it leave the phone? |
|---|---|---|
| Device list, names, rooms, scenes and routines | On your phone | No |
| Action history and device state | On your phone | No |
| Permissions and keys for your devices (TVs, cameras, boards, robots) | Encrypted on your phone | Only to that same device, on your network |
| Your AI key (Claude, Gemini or ChatGPT), if you set one | Encrypted on your phone | Only to that provider, when making a request |
| Brand account details, if you connect them (LG ThinQ, SmartThings, Smart Life / Tuya, SwitchBot, Home Connect, Electrolux, Miele, tado, Netatmo / Legrand / BTicino, Rachio, Google Nest, Govee; Somfy only once, to create local access, without storing the account) | Encrypted on your phone | Only to that brand's cloud, to import devices, read their state or send a command |
| Home Assistant, Zigbee2MQTT, FRITZ!Box, Nuki Bridge, IKEA DIRIGERA, Homematic hub, deCONZ gateway, Fire TV or Android device over ADB, Tedee Bridge, PowerView hub, Vizio TV, Somfy TaHoma box or Bosch Smart Home Controller (its password is used once and not stored), if you connect them | Encrypted on your phone | Only to your own server or broker |
| TP-Link email and password (Tapo devices), if you type them | Encrypted on your phone | No: the device only receives a hash |
If you don't type the Nuki Bridge IP, the app asks Nuki's discovery service (api.nuki.io) for it, which only sees your home's internet address.
DoSync creates no accounts and does not sell or share information. Its only server is Samuel's (optional, see below), which does not store your commands.
To find your devices, the app checks the addresses on your WiFi network and asks them what they are, and looks for nearby Bluetooth devices. That communication never leaves your home. The app does not use your location: to know whether you are home, it checks whether the phone is on your devices' network.
the command and a short list of your devices (type, room, possible actions and their state; no IP addresses or keys) are sent to the provider you chose. That request is governed by the provider's privacy policy (Anthropic, Google or OpenAI) and billed to your account with them. If you ask for something from the internet (a channel's latest video, the weather), that same provider runs the search with its own search tool. Without an AI configured, nothing is sent.
your devices go to DoSync's server (Cloudflare), which forwards them to Anthropic (Claude) to answer. The server stores no commands or answers: only an identifier of your Google Play subscription and how many credits you have left. Google Play processes the payment; DoSync never sees your payment details.
If you create a backup, the app builds a text encrypted with the password you choose and you share it wherever you want. DoSync does not receive it or keep a copy; without the password it cannot be read.
If you invite someone to a home, the app encrypts that home on your phone with a random key and uploads only the encrypted package to DoSync's server; the key travels in the code you share, never to the server, which cannot read it. The package is deleted as soon as someone uses the code (it works only once) or, if nobody uses it, after 7 days.
The app periodically downloads, from the public repository github.com/giulianireg-spec/dosync-adapters, a signed adapter catalog and the infrared code library. Those downloads include none of your data. When you connect a Miele account, its sign-in page returns you to a page on that same site that only shows the code for you to copy: it does not store or send it.
The app shows no ads and does not use the device's advertising ID. Tips ("Support development") and the Samuel subscription are charged by Google Play; DoSync does not receive your payment details.
You can delete everything by uninstalling the app, or remove devices, accounts and your AI key from the app at any time. Contact: rgiuliani@dosync.dev.
