Privacy Policy
Effective from 11 November 2026
Version 80d0f4cbac51
How the operator of Blindrelay processes personal data of its customers and website visitors, and the rights you have.
1. Who is responsible
The operator named at the end of this page is the controller for the personal data of Blindrelay account holders and website visitors described below. Contact us about your data at info@blindrelay.app.For the email you send through Blindrelay, you are the controller and we process it only on your instructions, as described in section 3.
2. What we process, why, and on what legal basis
- Account and sign-in: your email address, workspace name and role, the sign-in methods you set up (passkeys, the identifier and email of a linked Google, GitHub or GitLab account), and your active sessions with the browser and IP address they came from — to provide the service (performance of the contract).
- API keys and workspace configuration: key names, permissions and last use, sending domains, delivery and monitoring endpoints, inbound forwarding addresses and endpoints — to provide the service (performance of the contract).
- Billing: plan, subscription status and billing country; card and invoice details are collected by our payment provider — to take payment (performance of the contract) and to keep accounting and tax records (legal obligation).
- Security and abuse prevention: a log of account changes (who, what, when, from which IP address), delivery counters, one-way hashes of recipient addresses, and server logs, which can contain IP addresses and, when a service email cannot be queued, the account email address — our legitimate interest in keeping accounts secure, running the service reliably and protecting deliverability for all customers.
- Service emails: sign-in links and codes and notices about your account — performance of the contract.
- DMARC reports: when your domain's DMARC record names our report address, mailbox providers send us aggregate reports about mail using that domain. We keep the reporting organisation, report id, date range, sending IP addresses, message counts, the result and alignment of DKIM and SPF, and the domain in the From header, and we send you a summary — to provide the service (performance of the contract). These reports are processed in the EU only. We do not accept forensic (per-message) reports.
- New workspaces: if you answer "How did you hear about us?" when you sign up on our website, your answer from a fixed list (the question is optional). When a workspace is created, we send its name, the owner's email address, the plan and that answer to our own inbox so we can welcome new customers personally — our legitimate interest in learning which channels bring customers and in getting in touch with them.
- Offer claims: if you claim the migration discount or the founding-partner offer, the email address you give, which offer (and for the migration discount, which provider you are leaving), whether we approved it and when it was used — to decide on the claim and apply the discount at checkout (steps at your request before a contract and performance of the contract).
- Product feedback you choose to send (from the dashboard, the API, the command-line tool, or an AI agent using our plugin, which sends it only after you approve the draft): its rating, the product area, what you write about what worked or did not and what you were trying to do, whether a person or an agent wrote it, and which workspace and API key or user sent it. We refuse feedback that contains an email address. We may also receive it by email in our own inbox — our legitimate interest in improving the service.
- Messages you send to our contact address: your email address and what you write — our legitimate interest in answering you.
3. Email you send through Blindrelay
Message body, subject and headers are held in memory only for the delivery attempt and are never stored, with one exception: a message the recipient's mail server cannot take right away waits on disk, with its recipient address, for up to 24 hours and is deleted once it is delivered or expired. A workspace can turn this off; its messages then stay in memory and a temporary failure is final. Our mail server logs keep only the domain of a recipient address. Otherwise recipient addresses are replaced with a one-way hash before anything is stored, so we cannot read back your messages or your recipients. Requests from your recipients therefore go to you, as the sender. Mail received for your inbound aliases is handled the same way while it is passed on to the inbox or HTTPS endpoint you chose, including the wait on disk when an inbox defers it. See the security overview.4. Who receives data
Our hosting provider (OVHcloud, data centre in Frankfurt, Germany); our own monitoring server in the Czech Republic, which receives server logs; our payment provider (Stripe); the sign-in provider you choose (Google, GitHub or GitLab); Cloudflare, which runs our DNS and forwards email sent to our contact address; Google, which hosts the inbox for our contact address; the recipients' mail servers for the messages you send; and the inboxes and HTTPS endpoints you choose for mail to your inbound aliases. Public authorities receive data only where the law requires it. We do not sell personal data.5. Transfers outside the EU
Stripe, Google, GitHub, GitLab and Cloudflare may process data in the United States. Each is certified under the EU–US Data Privacy Framework, so these transfers rely on the European Commission's adequacy decision for it (Article 45 GDPR). Where a transfer is not covered by the certification, the standard contractual clauses in their data processing terms apply.6. How long we keep data
- Account, workspace configuration, API keys and suppression entries: until you delete them or the workspace.
- Sessions, with their browser and IP address: until the session ends or expires.
- Log of account changes: 90 days. Records of actions our staff take on a workspace: 12 months.
- DMARC aggregate report data, including sending IP addresses: 90 days, or until you delete the domain or the workspace.
- Server logs: 30 days.
- Messages waiting to be retried: up to 24 hours, then deleted (none if the workspace turned retries off).
- Delivery records: deleted when delivery finishes; bounce matching data and delivery counters up to 72 hours; recipient hashes used to detect list abuse up to 48 hours.
- Offer claims: until we decide on them; a rejected claim, or an approved one not used in time, for 12 months after the rejection or the end of the period to use it; a claim whose discount was used, for 10 years after it was used, as evidence for our accounts.
- New-workspace notices in our contact inbox (workspace name, owner email, plan, sign-up source): 12 months after they arrive.
- Product feedback you choose to send: 12 months after you send it.
- Invoices and payment records: 10 years, as Czech tax law requires; they are kept by our payment provider.
7. Your rights
You have the right to access your personal data, to have it corrected or erased, to restrict its processing and to receive it in a portable format. You can edit or delete most of it in the app, including deleting the whole workspace; for anything else write to info@blindrelay.app. We answer without undue delay, within one month at the latest.8. Right to object
You may object at any time to processing based on our legitimate interests (section 2). We will then stop, unless we show compelling legitimate grounds that override your interests, or need the data to establish, exercise or defend legal claims. You may object to direct marketing at any time, and we will stop.9. Complaints
You may lodge a complaint with the Czech Office for Personal Data Protection (uoou.gov.cz) or with the supervisory authority where you live or work.10. Whether you must provide data
An email address is needed to create an account, and billing details to buy a paid plan. Without them we cannot provide the service. No law requires you to provide them.11. Automated decisions
We do not make decisions with legal or similarly significant effects on you based solely on automated processing. Automatic abuse controls may pause sending for a workspace when its bounce or complaint rates exceed the plan's limits; a person reviews such a pause on request at info@blindrelay.app.12. Storage in your browser
The app stores in your browser only what it needs to work — your sign-in, preferences, the page to return to after signing in, a newly created API key until you close the tab, and notices you dismissed — and uses no tracking or advertising cookies and no third-party scripts, so no consent is needed.13. Changes to this policy
We update this policy when our processing changes. The effective date and the version shown at the top identify the current text.See also: Terms of Service and Acceptable Use Policy .
