This Privacy Policy explains how Baumeister Private Server, Inc., a Delaware corporation ("Baumeister," "we," "us," or "our"), handles information in connection with the Baumeister Private Server self-hosted software and any optional hardware kit (together, the "Software"). It applies only to the self-hosted Software. A separate Privacy Policy governs Baumeister's hosted website-building and hosting service, where the roles described below are different. This Policy is incorporated into the End User License Agreement for the Software.
The Software runs on your own device. The site you build, and the data your site collects from its visitors, are stored on your device, not on Baumeister systems. The Software does not send Baumeister telemetry about how you use it. As a result, most information stays with you, and Baumeister collects only the limited information described in Section 2. Some features you choose to use, such as email alerts, Safety Net, site sign-in, Help, and free AI updates, involve Baumeister systems handling limited information, including in some cases information about your site's visitors, as explained in Sections 2 and 3.
Free use with your own AI key. If you use the Software without a paid feature and connect your own AI provider key, Baumeister does not require an account and does not collect your site content. The Software still makes three kinds of request. It checks for updates by contacting GitHub, Inc., which hosts our releases; that request reveals your IP address and the Software version to GitHub. Each time it starts, it downloads the current list of AI models from Baumeister, which reveals your IP address to us. And once, when it is first able to reach us, it registers its installation identifier and proof with Baumeister (see Device identifiers below), with a stand-in email address made from that identifier rather than your own. None of these requests include personal information about you beyond your IP address.
Device identifiers. Each installation of the Software creates a random installation identifier and a secret that proves requests come from that installation. When the Software contacts Baumeister systems for any feature described in this Policy, it sends that identifier and proof, and in many cases your device's name (for example, the computer name you see in Windows or macOS), so that we can tell your devices apart, show them to you, and secure your account.
Account and billing. If you buy a paid plan, such as a plan for additional web addresses, buy a domain name through us, or buy a hardware kit, we collect the information needed to create your account and process payment, such as your email address and billing details. Payments are processed by Stripe, Inc., and we do not store full payment card numbers. To confirm which plan applies to you, Baumeister systems may look up your plan with Stripe using your email address. If you register a domain name through us, the registrant contact details the registration requires, such as your name, postal address, telephone number and email address, are sent to our domain registration provider, Tucows Inc. (OpenSRS), and to the relevant domain registry as the registration rules require. These registration requests pass through a server we operate with DigitalOcean, LLC, which forwards them to the registration provider and does not store them.
Help. The Software includes a Help assistant that you, and people you have added to your Software, may use. When it is used, the recent messages in that conversation (which may include text you or they paste in, such as an error message), together with your email address and installation identifier, are transmitted through Baumeister to our AI provider so it can return an answer. We do not store the content of Help conversations. We keep counts of how much Help each account and each network address uses, so that we can apply fair-use limits.
Free AI updates (optional). The Software may offer a limited number of free AI updates each month, which use Baumeister's AI provider to make changes you request to a website you build with the Software. This feature is off unless you turn it on, and it is available only while your device has a verified email address and you have not connected your own AI provider key; connecting your own key turns it off. Each time you request an update, the Software sends Baumeister your request, the files of that website needed to make the change, your email address and your installation identifier. Baumeister transmits your request and those files to our AI provider so that it can return the changes, which the Software saves on your device as a draft for you to review. The Software does not send hidden files, files that appear to contain passwords or keys, or the form submissions and other data your site stores from its visitors, but the files of your website may include personal information that appears on your website. We do not store your requests, your files or the returned changes. We keep counts of how many free AI updates each account, installation and network address has used, so that we can apply the monthly limit and prevent abuse.
Support. If you contact us, we receive the information you choose to provide, such as your email address and the contents of your message.
Recovery email. When you set up the Software, you provide a recovery email address. It is sent to Baumeister, with your device's name, so that we can email you a code if you forget your password, send a one-time confirmation when you set it up, notify the previous address if it is changed, and send a code to re-confirm your device if its security credentials need to be restored. We use it only for these purposes.
Verified email and your devices. If you verify an email address in the Software (for example, under Settings > Email & computers) to use a paid plan or to link more than one device, we keep that email address and a list of the devices linked to it, including each device's name, when it was added and when it was last seen, so that we can show you your devices and let you remove them.
Optional contact email. When you publish your first web address, you may choose to share that same email address with Baumeister so that we can contact you about your sites, including to tell you if a site with Safety Net turned on is being shown from Baumeister systems because your device is off. This is optional, is off unless you select it, and can be turned off at any time in Settings.
Web addresses. When you publish a site or app at a web address we provide, or connect your own domain name, we keep a record of the address, the account email it belongs to, the installation and device it points to, and the technical settings needed to route it (such as tunnel and DNS records with Cloudflare, Inc.). When you release an address, we stop routing it and delete its routing settings, but we may keep a record that the address was held by your account, so that we can resolve disputes about who may use it and prevent abuse.
Email alerts for your site's forms. If your device has a verified email address, the Software can email you when a visitor submits a form on your site, such as an order or a message. You choose in the Software whether alerts include the visitor's answers (the default), only a short notice, or nothing. When alerts include answers, the Software sends Baumeister the site name, the form's name, the visitor's answers (up to 40 fields), and the visitor's email address, if they gave one, so that you can reply to them directly. Photos and files are not sent. Baumeister passes the alert to our email delivery provider, Resend, to send to you. We do not store the alert's contents on Baumeister systems, but our email delivery provider keeps a copy of sent emails for a limited period under its own terms.
Site sign-in. If you turn on sign-in for a site, so that only visitors you approve can view it, a visitor who signs in enters their email address on a page served by Baumeister, and we email them a one-time code through our email delivery provider. We keep the code for up to 10 minutes and the visitor's signed-in session, which includes their email address, for up to 30 days, and we pass the visitor's email address to your device so your site knows who is signed in. To block automated abuse, that page uses Cloudflare Turnstile, which receives the visitor's IP address.
Checking on your device from your phone (optional). If you turn this on, the Software sends Baumeister a status report about every minute, including your device's name, operating system, Software version, processor, memory and disk use, uptime, the names and states of your apps, your public web addresses and, for hardware kits, hardware health readings, so that you can see them from another device. We keep each report for up to 7 days.
Hardware kit setup. While a Baumeister hardware kit is being set up, it contacts Baumeister systems every few seconds, sending its installation identifier, software version and setup email. To let you find your kit from a phone or computer on the same network, we record the public IP address (or the network part of an IPv6 address) of the network the kit is on. After setup, the kit contacts Baumeister systems each time it starts and once a day for as long as it remains set up, sending the same installation identifier, software version and email, so that we know the kit is still in use. We record when it last did so. These contacts stop when the kit is reset.
Backups to another device (where available). If you send backups to another device you own, the backup files travel directly between your devices over their tunnels and are not stored on Baumeister systems. We keep the information needed to connect the two devices, such as the receiving device's name, its account email and a one-time pairing code, until you turn the feature off.
Safety Net (optional). Safety Net is off unless you turn it on for a published site or app, and turning it on requires you to confirm that you understand the site will be stored on Baumeister systems. While it is on, the Software sends Baumeister one of the following: (a) the public files of that website, meaning the pages, images and other files any visitor can already see; (b) for an app, a copy of the pages the app shows to a visitor who is not signed in, made by visiting those pages the way such a visitor would, which may include any information the app displays publicly; or (c) a "Back Soon" page you write. Baumeister stores them to show them to visitors while your device is off or not responding, or, if you choose the option to always serve the site's public files from Baumeister, at all times, along with the time you turned the feature on, any of your own domain names connected to the site, and a count of how many visits were served that way. The Software does not send hidden files, files that appear to contain passwords or keys, or the form submissions and other data your site stores from its visitors. When you turn Safety Net off, unpublish the site, or release its address, Baumeister deletes the stored files.
Security and abuse prevention. To protect the Software, our systems and other users, Baumeister systems record the IP addresses that make requests to them, including requests from your site's visitors, for short periods in order to apply rate limits, and keep records of any action we take against content or accounts that violate our terms, such as a takedown.
When your site collects personal information from its visitors, such as contact form submissions, messages, order and transaction records, and any files or documents stored through the Software, that information is written to and stored on your device. Baumeister does not collect it as telemetry and does not store it on Baumeister systems, except as follows: (a) if you use email alerts, the visitor's form answers and email address pass through Baumeister and our email delivery provider to reach you, as described in Section 2; (b) if you use site sign-in, we handle the visitor's email address and sign-in session as described in Section 2; (c) if you turn on Safety Net for an app, the copy we store may include information the app displays publicly; (d) visitor requests to web addresses we provide pass through Baumeister systems as described in Section 5; and (e) if you use an AI feature of the Software to process content, that content may include personal data your site has collected, and it may be transmitted to the applicable AI provider, and in the case of Help or free AI updates through Baumeister, to perform the task you request. As between you and Baumeister, you are the controller of that information, and Baumeister handles it on your behalf only to provide the features you choose. You are responsible for handling that information in compliance with applicable law, including giving your visitors your own privacy notice and answering their requests to exercise their rights.
The Software works with third-party AI providers. When you supply your own provider key, your content goes from your device directly to the provider you selected, under that provider's terms, and Baumeister does not receive it. When you or people you have added use Help, or when you use free AI updates, your content is transmitted through Baumeister to our provider, Anthropic, PBC, whose commercial terms provide that it does not use inputs or outputs to train its models. Each provider's own privacy terms govern its handling of the content it receives.
When you publish your site, the Software makes it reachable through a Cloudflare Tunnel. Visitor traffic to your site passes through Cloudflare, Inc. in transit before it reaches your device. When your site uses a web address we provide, that traffic also passes through Baumeister's systems, which run on Cloudflare, so that we can route it to your device, add features such as site sign-in, Safety Net and a link visitors can use to report abuse, and apply the security measures described in Section 2. Baumeister does not keep a copy of the pages or form submissions in that traffic, apart from the specific features described in Section 2, but our systems may keep short-lived technical logs. Because your visitors' data passes through Cloudflare and Baumeister on the way to you, you should describe this in the privacy notice you give your visitors.
We use the limited information we collect to deliver and secure the Software and its updates; to route your web addresses and provide the features you choose, such as email alerts, Safety Net, site sign-in, Help, free AI updates, backups to another device and checking on your device from your phone; to provide paid plans and process payments; to send you the codes, confirmations and notices described in this Policy; to respond to your support requests; to detect and prevent fraud and abuse and enforce our terms; and to comply with legal obligations.
We do not sell your personal information, and we do not share it for cross-context behavioral advertising. We share the limited information we hold only with vendors that help us operate, namely Cloudflare, Inc. for hosting, networking and security (including Cloudflare Turnstile); Resend for email delivery; Stripe, Inc. for payment processing; Anthropic, PBC as our AI provider for Help and free AI updates; Tucows Inc. (OpenSRS) and the relevant domain registries for domain registration; DigitalOcean, LLC for the server that forwards domain registration requests; and GitHub, Inc. for delivering Software updates; when required by law or legal process; and in connection with a merger, financing, or sale of assets, subject to this Policy.
We retain account and billing information for as long as needed to provide paid features and to meet legal, tax, and dispute-resolution obligations, then delete or de-identify it. We keep your recovery email, verified email, device records and web address records while your installation or account is in use, and for as long as needed afterward to resolve disputes and prevent abuse; you can remove a device under Settings > Email & computers. Other information is kept for the shorter periods stated in Section 2, including one-time codes for minutes, site sign-in sessions for up to 30 days, and device status reports for up to 7 days, counts of free AI updates for no more than two months, and rate-limit records of IP addresses generally for no more than about six weeks. Our email delivery provider keeps copies of emails it sends for a limited period under its own terms. Apart from the features described in Sections 2 and 3, we do not retain the data your site collects from its visitors, because that data stays on your device.
Depending on where you live, you may have rights to access, correct, delete, or obtain a copy of the personal information Baumeister holds about you, and to opt out of the sale or sharing of personal information. We do not sell or share personal information. To exercise a right regarding information Baumeister holds, contact us at info@baumeisterprivateserver.com, and we will respond as applicable law requires. For the data your site collects from its visitors, you are the controller, and your visitors should direct their requests to you; where Baumeister handles some of that data on your behalf as described in Section 3, we will help you respond as applicable law requires.
We use reasonable technical and organizational measures to protect the limited information we hold. No method of transmission or storage is completely secure, and we cannot guarantee absolute security. Because your site and its data reside on your device, you are responsible for securing your device and that data, including through access controls, encryption, and backups.
The Software is intended for users who are at least 18 years old. We do not knowingly collect personal information from children under 13. If we learn that we have done so, we will delete it.
We may update this Policy from time to time. We will post the updated Policy with a new "Last updated" date, and for material changes we will provide additional notice. Your continued use of the Software after the changes take effect constitutes acceptance of the updated Policy.
