In short: Your drawings stay in your browser on your computer. They only reach our server if you save them yourself under "My projects" or as a custom symbol in your account (section 4) or use an AI tool (section 8); saved projects and symbols are visible only to you and are deleted together with your account. Apart from that, we only store what is needed for your account. There are no ads, no tracking, no analytics tools and no cookies except for login, language choice and taking you straight to the app. You can use the editor without any account.

No data protection officer has been appointed, as there is no legal obligation to do so.
When you visit beamsketch.com, our server processes your IP address, date and time, the requested address and the browser identifier as technically necessary to deliver the page and secure the connection (Art. 6(1)(f) GDPR – legitimate interest in a secure and functioning service). We do not keep permanent access logs. To protect against attacks (e.g. password guessing), the IP address is counted briefly in memory and discarded after one hour at the latest. Technical error messages of the server may be stored in the system log for up to 14 days.
To see how BeamSketch is used, we count visits to the start page and the app as plain daily totals (e.g.
"120 app visits on 31 October"). We store nothing about you: no IP address, no identifier, no additional cookie.
Whether the app has been opened before is derived only from the existing ls_app cookie (section 5);
no conclusions about individual persons are possible.
The connection is encrypted via HTTPS.
The server is located in a data centre in Germany operated by IONOS SE, Elgendorfer Str. 57, 56410 Montabaur, Germany. A data processing agreement pursuant to Art. 28 GDPR is in place with IONOS.
You can use the editor without an account. If you create an account (to save projects and symbols on our server or for the AI tools), we store:
Saved projects and symbols are visible only to you. You can delete them in the app at any time; deleting your account deletes all projects and symbols.
The legal basis is the performance of the user contract (Art. 6(1)(b) GDPR). The data is stored until you delete your account (possible at any time under My account). When you delete your account, the account data is removed immediately; it remains in backups for no more than 30 days.
We set up to three cookies: ls_sid keeps you logged in after login (30 days at most);
ls_lang stores the language you chose or use the app in (e.g. "en", 1 year at most) so that our pages
and emails appear in that language; ls_app remembers, without login, that you have already opened
the app (value "1", 1 year at most) so that beamsketch.com takes you straight to the app on your next visit. All of
them are technically necessary (§ 25(2) no. 2 TDDDG) and are not used for tracking.
The app also stores your current drawing, settings, material library and language in your browser's local storage (localStorage); you can delete it at any time in your browser settings. Drawings are only sent to our server when you save them as a project (section 4) or use the AI tools (section 8).
We only send you emails related to your account: email confirmation, password reset, deletion confirmation. We do not send newsletters or advertising. We use the service Brevo (Sendinblue SAS, 106 boulevard Haussmann, 75008 Paris, France) for sending. Brevo receives your email address and the content of the message; a data processing agreement is in place with Brevo. Legal basis: Art. 6(1)(b) GDPR.
If you write to us at support@beamsketch.com, we process your message in order to reply (Art. 6(1)(b) or (f) GDPR) and delete it once the request has been dealt with and no retention obligations apply.
The same applies to "Report a bug" in the app: we receive your message, the email address you optionally provide, your account email if you are logged in, and your browser identifier, language and selected laser so we can reproduce the problem. The message is not stored but forwarded to us by email (via Brevo).
BeamSketch is free of charge. We do not process any payment data.
The AI tools are optional, only available with an account and only work when you explicitly start them. They run on your own API key at OpenAI (OpenAI Ireland Ltd., 1st Floor, The Liffey Trust Centre, 117–126 Sheriff Street Upper, Dublin 1, Ireland). The app stores the key only in your browser's local storage (in your account's area; it is deleted when you log out). With every request, the app sends it together with your text (the description or requested change) and, for AI Lasso, a black-and-white image of the circled lines to our server; the server passes the request on to OpenAI with your key and returns the drawing. We do not store or log the key. Your email address, name or other account data are not transmitted to OpenAI. Processing at OpenAI takes place via your own OpenAI account under your contract with OpenAI and its privacy terms (OpenAI privacy policy); where data reaches the USA, this is based on the EU-US Data Privacy Framework or the EU Standard Contractual Clauses. Legal basis for the forwarding by our server: Art. 6(1)(b) GDPR. Please do not enter personal data into the text fields.
Before every AI request, our server checks the text and, where applicable, the selection with OpenAI's checking service (Moderation) for violations of the usage rules (Terms § 5). If a request is rejected, we store the time, the rejected text and the reason with your account in order to detect misuse and to be able to disable the AI tools after repeated violations (Art. 6(1)(f) GDPR; legitimate interest: protection against misuse and compliance with our service providers' rules). We delete these entries after 90 days.
The USB connection to your laser runs directly between your browser and the machine (Web Serial). GCode and machine data are not transferred to our server.
You have the right of access (Art. 15 GDPR), rectification (Art. 16), erasure (Art. 17), restriction of processing (Art. 18), data portability (Art. 20) and to object to processing based on legitimate interests (Art. 21). An informal email to support@beamsketch.com is sufficient.
You can also lodge a complaint with a data protection supervisory authority, e.g. the authority responsible for us: Landesbeauftragte für Datenschutz und Informationsfreiheit Nordrhein-Westfalen, Kavalleriestr. 2–4, 40213 Düsseldorf, Germany, ldi.nrw.de.
No automated decision-making or profiling takes place.
