Privacy Policy
Last updated: 21 September 2026
Who We Are
ArchPlug is operated by ArchPlug DOO Beograd-Zvezdara, a company registered in the Republic of Serbia (company reg. no. / MB 22315285, tax ID / PIB 115780969), Jovanke Radaković 118, 11160 Belgrade, Serbia. ArchPlug DOO is the data controller for the personal data described below. Contact: support@archplug.com.
This policy explains what data we collect, why, how long we keep it, and your rights under the Serbian Personal Data Protection Act (ZZPL) and, where it applies to you, the EU General Data Protection Regulation (GDPR).
Data We Collect and Why
- Your ArchPlug account — when you register: your email address, a securely hashed password (we never store the password itself), and the one-time codes used to verify your email or reset your password. Used to sell you licences, keep your downloads available and let you log in. Legal basis: performance of a contract.
- Trial and licence records — the email address you enter in ArchPlug Settings, which plugins you are trying or have bought, trial start dates and purchase records. Used to deliver trials and licences and to provide support. Legal basis: performance of a contract.
- Licence verification — when a plugin checks your licence, it sends our server your licence email, a machine identifier (a one-way hash derived from your computer name and Windows user name; the names themselves are not sent in this check), the plugin and its version. To prevent the same trial from being restarted with new email addresses, we remember when a machine identifier was first seen. Legal basis: performance of a contract and our legitimate interest in preventing licence abuse.
- Software updates and installation status — the ArchPlug Updater helper installed with the plugins runs under your Windows account, also while Revit is closed. So that updates actually arrive and we can see why one fails, it sends our server:
- your licence email and the machine identifier described above;
- the computer name, and whether the Windows account has administrator rights. The Windows user name is not sent; older versions of the helper did send it, and our server discards it on receipt (together with user names inside file paths), so it is never stored.
- Windows and PowerShell versions, which Revit versions are installed, and whether Revit is currently running (process start time and version);
- the installed ArchPlug plugins with their versions, file checksums and install folders, and the state of the updater itself;
- update events: when an update was downloaded, installed, refused or failed, with the technical reason, and when Revit was started or closed.
If you clear the email field in ArchPlug Settings, the helper stops downloading updates and stops sending your email; until it is removed it still sends the technical status above, without an email address. When you uninstall the plugins, the helper removes itself within about an hour. To have the stored status of your computer deleted, write to support@archplug.com. - Error reports (optional, only with your consent) — if a plugin encounters an error, it asks whether you want to send an error report. A report contains: plugin name and version, Revit version, Windows version, the machine identifier, a one-way hashed identifier of your account (not your email address), and the technical error details. It contains no name, no email address and no project data: project and view names are not included, and Windows user names, project folders and names of project files are removed from error messages before sending. Nothing is sent unless you choose “Send this report” or “Always send”, and you can change your choice at any time in ArchPlug Settings › Privacy. Legal basis: consent.
- Usage statistics (optional, only with your consent) — only while “Always send” is on (chosen after an error, switched on in ArchPlug Settings › Privacy, or set by your company’s IT policy), the plugins also send usage statistics: which plugin commands were used and how often, the plugin version, the Revit and Windows version, a one-way hashed identifier of your account (not your email address) and the machine identifier. They contain no project data, no file names and no content from your Revit models. We use them to see which tools are used and on which Revit versions, so we know what to fix and test first. Without your consent nothing is counted or sent, and it stops as soon as you switch it off. Legal basis: consent.
- Payments — purchases are processed by Paddle.com as merchant of record (earlier purchases: PayPal). Paddle collects your payment and billing details directly; we never see or store your card details. We receive the email address, the product bought, the amount, the transaction reference and the name of the channel through which you found our site (see our Cookie Policy). See Paddle’s privacy policy. Legal basis: performance of a contract and legal obligations (accounting).
- Student & teacher discount — if you apply, we store your email address and the proof document you upload (e.g. a student ID or certificate), which may contain your name, photo and school. It is used only to decide on the discount and is stored in a folder not accessible from the web. Legal basis: steps taken at your request before entering into a contract.
- Newsletter — if you subscribe, we store your email address and send you news about ArchPlug. Every newsletter contains an unsubscribe link. Legal basis: consent, which you can withdraw at any time.
- Service emails — to customers and trial users we send emails that are part of the service: download links, licence and account messages, and notices about important updates to plugins you use. These are not marketing.
- Support — when you email us, we keep the correspondence to answer you and handle later questions about the same issue. Legal basis: performance of a contract / legitimate interest.
- Server logs — like most websites, our server records technical logs of requests (time, address requested, IP address and technical outcome) to keep the site secure, prevent abuse and fix faults. Legal basis: legitimate interest.
We do not sell or rent personal data, and we do not use your email for marketing unless you have subscribed to the newsletter.
AI Features (ArchPlug Agent)
Some of our products — in particular ArchPlug Agent — are powered by a third-party large language model, Anthropic’s Claude. When you use such a feature, you are interacting with an artificial intelligence system rather than a human being; this is also stated in the product interface.
- What is sent — the instruction you type, and the context from your open Revit model that is needed to carry it out (for example element names, types, parameters and dimensions relevant to your request). This is transmitted to Anthropic in order to generate a response. Legal basis: performance of a contract (you asked the feature to run).
- What is not sent — we do not upload your Revit project file (
.rvt) itself, and we do not send your name, email address or licence data to the AI provider. - When it is sent — only when you explicitly run an AI-assisted action. No AI feature runs on its own. (Licence checks and software updates, described above, never include anything from your Revit models.)
- Who processes it — Anthropic, PBC (United States) acts as our processor for these requests. Under its commercial terms Anthropic does not use data submitted through its API to train its models. See Anthropic’s privacy policy.
- We do not store your prompts. ArchPlug does not keep a copy of the instructions you give the Agent or of the model context sent with them. A local counter of how many tokens you have used is stored only on your own computer.
- Your choice — AI features are optional. If you do not use them, no data is sent to any AI provider.
AI output can be inaccurate and must be reviewed before you rely on it — see the AI-Assisted Features section of our Terms of Service Refund Policy Cookie Policy.
Website AI Assistant (“Ask AI”)
The chat window in the bottom-right corner of this website is an artificial intelligence assistant, not a human being, and this is stated in the chat window itself. It answers pre-sales questions about our plugins, pricing and licensing. Its answers can be inaccurate; for anything binding, the prices and terms published on this site and in our Terms of Service prevail.
- What is sent — the message you type and the earlier messages of that same chat, together with the page you are reading. This is transmitted to Anthropic, PBC (United States), acting as our processor, in order to generate the reply.
- What we store — we keep a log of the questions asked here and the answers given, so we can see what our documentation fails to explain, together with the page, the time, and a one-way hash of your IP address used for rate limiting. Legal basis: our legitimate interest in improving the product and preventing abuse.
- Please do not type personal or confidential information into the chat. Use support@archplug.com instead.
- If you leave your email — when the assistant cannot answer, it offers to pass the question to a person. If you give your email address, we store it with that chat and use it solely to reply to you. Legal basis: steps taken at your request before entering into a contract.
- Your choice — the assistant only runs when you open it and type something.
Who Processes Data for Us
- Web hosting and email delivery — our hosting provider, whose servers for this site are in the European Union.
- Paddle.com — payments, invoicing and tax, as merchant of record (independent controller for payment data).
- Anthropic, PBC (United States) — AI features described above.
- Our accountants — purchase records, as required by Serbian accounting law.
ArchPlug DOO is based in Serbia, which the European Commission has not formally recognised as providing adequate protection, although its law (ZZPL) is closely modelled on the GDPR. We apply GDPR-level safeguards to all personal data. Transfers to the United States (Anthropic) rely on the Standard Contractual Clauses approved by the European Commission.
Data Retention
- Account, licence and purchase records — for as long as your account or licence exists; purchase and invoice records for as long as accounting and tax law requires (in Serbia, up to 10 years).
- Trial records and machine identifiers — for as long as needed to apply the one-trial rule, and deleted on request if you have not bought anything.
- Updater status and update events — the latest status of each computer is kept while the helper is in use; the history of events is kept for up to 12 months.
- Error reports, usage statistics, Ask AI logs and server logs — up to 12 months.
- Student & teacher proof documents — until the request is decided and for as long as the discount is in use; deleted on request.
- Newsletter — until you unsubscribe.
Cookies
This website uses only its own cookies and browser storage: to keep you logged in, and to remember the channel through which you found us. We do not use third-party tracking, advertising or analytics cookies. Payment and video providers embedded on the site may set their own cookies. Details: Cookie Policy.
Your Rights
You have the right to:
- Access the personal data we hold about you
- Request correction or deletion of your data
- Restrict or object to processing based on our legitimate interest
- Withdraw consent at any time (e.g. turn off error reports or unsubscribe from the newsletter), without affecting processing done before
- Receive your data in a portable format
- Lodge a complaint with a supervisory authority — in Serbia the Commissioner for Information of Public Importance and Personal Data Protection (poverenik.rs), or the data protection authority of your EU country of residence
Note that deleting your account or licence data ends the licence, because the licence is tied to it. To exercise any of these rights, email support@archplug.com. We respond within 30 days.
Security
Passwords are stored only as secure hashes, our data files are not accessible from the web, and connections to our server use HTTPS. No system is perfectly secure; if a breach affecting your data occurs, we will inform you and the authorities as the law requires.
Changes
We update this policy whenever what our software sends changes. The date at the top shows the latest version; material changes are announced to customers by email.
