These Terms govern your use of Nullsend. By creating an account or using the service, you agree to them. We have written them in plain language, because terms you cannot understand are not terms you can trust.
Nullsend Ltd is a company registered in England & Wales with company number 17266592. References to "Nullsend", "we", "us" and "our" mean Nullsend Ltd.
Nullsend is an encrypted file transfer service. Files are encrypted in your browser before they leave your device, so our systems only ever hold ciphertext. We cannot read the contents of the files you send. The key needed to decrypt a file lives in the share link and is never sent to our servers.
The service is provided on a business-to-business basis, to organisations and people using it for their work, not as a consumer product.
You are responsible for your account, for keeping your password secure, and for activity that happens under your account. Because of how the encryption works, we cannot recover the contents of an encrypted file if the decryption key in its share link is lost. Keep your share links safe; treat them as you would the files themselves.
You must give accurate account information and keep it up to date. You must be old enough to enter a contract in your jurisdiction, and authorised to accept these Terms on behalf of any organisation you represent.
You agree not to use Nullsend to:
Because files are encrypted and we cannot see their contents, enforcement of this section relies on reports and on the metadata available to us. Anyone, whether or not they hold an account, can report suspected illegal content or misuse of the service using our report form at app.nullsend.io/report. If we become aware that an account is being used in breach of these Terms, we may suspend or close it (Section 8). Where we suspend an account, the account holder may appeal and ask us to review the decision. To report a child in danger or child sexual abuse material, please use the specialist services signposted on our Child Safety page rather than the report form.
Your files and data remain yours. We claim no ownership of, and no rights over, the content you send through Nullsend beyond what is strictly necessary to operate the service (storing the ciphertext, delivering it to your recipient, and showing you the metadata of your transfers). We do not use your content to train artificial intelligence or machine learning models, we do not sell it, and we cannot read it. Where we process personal data contained in your files on your behalf, that processing is governed by our Data Processing Agreement.
We work to keep the service available and reliable, but we provide it "as is" and do not guarantee uninterrupted or error-free operation. We may carry out maintenance, and we may update, improve, or change features over time. If we make a change that materially reduces the core functionality you are paying for, we will give you reasonable notice.
Files are deleted automatically on the expiry schedule you set, or on first download where you choose that option. Once a file has expired or been deleted, it cannot be recovered.
Paid plans are billed monthly in advance through our payment provider, Stripe. Prices are shown on our site, exclusive of VAT where applicable. By subscribing, you authorise us to charge the plan fee, and any usage overage at the published rate, to your payment method on each billing cycle.
Subscriptions renew automatically each month until cancelled. You can cancel at any time, and your plan will run to the end of the current paid period and then stop. We do not provide pro rata refunds for partial months unless required by law. We will give reasonable notice of any price change before it takes effect.
If a payment fails, we may suspend the account until payment is resolved, following a reasonable grace period.
Our handling of personal data is described in our Privacy Notice. Where we process personal data on your behalf as your processor, our Data Processing Agreement applies and forms part of these Terms. Both are available on our site.
You may close your account at any time. On closure, we delete the personal data we hold for you in line with our Privacy Notice and Data Processing Agreement.
We may suspend or close an account if it is used in breach of these Terms, if it poses a security or legal risk, or if required by law. Where it is reasonable and lawful to do so, we will give notice and an opportunity to put things right first. We may also withdraw the service entirely with reasonable notice, in which case we will allow you to retrieve outstanding transfers where possible and will refund any prepaid fees covering the period after withdrawal.
Nothing in these Terms limits liability that cannot be limited by law, including liability for death or personal injury caused by negligence, or for fraud.
Subject to that, the service is provided without warranties beyond those that cannot be excluded by law, and we are not liable for indirect or consequential losses, loss of profits, loss of business, or loss of data beyond what we hold. Our total liability to you for any claim arising out of or in connection with the service is limited to the amount you paid us for the service in the twelve months before the event giving rise to the claim.
You are responsible for keeping your own copies of files you send; the service is a transfer tool, not a backup or archive.
These Terms are governed by the laws of England and Wales, and the courts of England and Wales have jurisdiction, unless mandatory law in your country provides otherwise.
We may update these Terms. If we do, we will change the date above and, for material changes, take reasonable steps to notify you before they take effect. Continuing to use the service after a change means you accept the updated Terms.
