By using otpbox.io ("OTPBox", "we", "us"), you agree to these terms. If you don't agree, please don't use the service.
OTPBox generates a temporary, receive-only email address with no sign-up. It is meant for one-time codes, confirmations and low-stakes sign-ups where you don't want to give out your real address. Addresses stop working, and their messages disappear from your view, 1 hour after creation. There is no way for you to recover a message after that window closes. For abuse prevention and security we keep a copy of each inbox and its messages for 30 days, then permanently delete it (see the Privacy Policy).
You may not use OTPBox to:
We may suspend or block access, remove content, or report activity to the relevant authorities if we believe these terms are being violated.
OTPBox is provided "as is," free of charge, with no guarantee of uptime, delivery, or that any specific email will be received or displayed correctly. Some services actively block known disposable-email domains, including otpbox.io, and we cannot guarantee delivery from every sender.
To the maximum extent permitted by law, OTPBox and its operator are not liable for any loss or damage arising from your use of, or inability to use, the service, including missed messages, lost access, or reliance on OTPBox for anything sensitive. Use it at your own risk, and never for anything you can't afford to lose access to.
Messages sent to an OTPBox address are sanitized (scripts, forms and remote images are stripped) before display, but we cannot guarantee every message is safe. Treat unexpected attachments and links with the same caution you would in any inbox.
A developer API is available at /api/v1 for both a free tier and a paid, quota-metered subscription. Automated use of the web app itself (as opposed to the published API) beyond reasonable, good-faith testing is not permitted and may be rate-limited or blocked. Paid API access (the Pro plan) is bought for an organization from the dashboard at /app, is billed monthly through Paddle and renews automatically until cancelled; cancel from your organization's Plan & usage card in the dashboard, or email billing@otpbox.io. Plans and quotas are described on the pricing page. Refunds are covered by our Refund Policy.
Premium is a paid add-on (ad-free browsing and longer inbox retention) billed monthly or annually through Paddle. There is no account or password: after purchase you receive a single premium key, shown once, which you enter in the app to unlock the perks on that browser. Treat this key like a password — anyone who has it can use your premium perks. We may revoke a key we reasonably believe is being shared or abused. If you lose your key, email billing@otpbox.io from the address used at checkout and we will verify the purchase and issue a new one; we cannot recover a lost key any other way, since we never store it in a form we can read back. Premium renews automatically until cancelled; use the in-app "Manage subscription" button, or email billing@otpbox.io. Refunds are covered by our Refund Policy.
We may update these terms as the service changes. Continued use after an update means you accept the revised terms. We'll update the date at the top of this page when that happens.
