Privacy Policy

1. Who we are

Skypost (“we”, “us”) runs the file transfer service at skypost.co.uk, including the website, installable app and API. For the purposes of the UK General Data Protection Regulation (UK GDPR) and the Data Protection Act 2018, we are the controller of the personal data described in this policy.

  • Skypost is run by its owner, a sole trader based in the United Kingdom. It is not a limited company.
  • A postal address for legal notices is available on request by email.
  • Email: [email protected]

We have not appointed a Data Protection Officer. Questions about privacy go to the email above.

2. Team and business accounts

If you use Skypost through a team or business account, the organisation that runs the team decides how files shared in that team are used. For that content the organisation is the controller and we act as its processor, handling it only to provide the service. Ask the organisation about how it uses your data. We remain the controller for account, billing and security data.

3. What data we collect

a) Account data (if you create an account)

  • Name (optional) and email address
  • Password, stored only as a secure hash, never in plain text
  • Plan, settings, notification preferences and the date you accepted our terms
  • Team membership, team branding and API keys (stored as hashes) if you use those features

b) Files and folders

  • The files you upload, and their names, sizes and types
  • Folder details such as labels, subfolders, expiry dates and access words or links
  • Access records, for example when a folder is opened or a file is downloaded

Please do not upload special category data (such as health records) about other people unless you have a lawful basis to share it.

c) People you send folders to

If you use our email, SMS or WhatsApp sharing, we use the recipient’s email address or phone number only to deliver that message. We keep a masked version (for example j***@example.com) to show delivery status. If you share someone’s contact details, make sure they would expect to hear from you.

d) Messages you send us

  • Contact form and enterprise enquiries (such as your name, email, company and message)
  • Abuse reports (the reason, details and, if you choose to give it, your email)

e) Technical data

  • IP address, stored as a one-way hash rather than the raw address
  • Browser and device information (user agent)
  • Security and audit logs, and API usage logs if you use the API
  • Push notification subscription details, if you turn notifications on
  • Page visit counts: we count how many times each page is viewed per day. This uses no cookies and stores no IP address or identifier, only the page and a daily total

f) Payments

Payments are handled by Stripe. We store your Stripe customer ID and subscription details. We never see or store your full card details.

4. Why we use your data and our lawful basis

UK GDPR requires a lawful basis for each use of personal data. Ours are:

PurposeLawful basis
Storing, encrypting and delivering your filesContract: needed to provide the service you asked for
Creating and running your account, team and planContract
Taking payments and managing subscriptionsContract
Sending share messages to the recipients you chooseLegitimate interests: delivering the files you asked us to send
Service emails (password resets, security and billing notices)Contract and legitimate interests
Preventing abuse, fraud and attacks; rate limiting; security logsLegitimate interests: keeping Skypost and its users safe
Handling abuse reports and removing illegal contentLegal obligation and legitimate interests
Counting page visits (anonymous daily totals)Legitimate interests: understanding which pages are used
Replying to enquiries and support requestsLegitimate interests
Keeping tax and accounting recordsLegal obligation
Responding to lawful requests from police, courts or regulatorsLegal obligation

Where we rely on legitimate interests, we have balanced them against your rights. You can ask us for details of that assessment. Account data is needed to provide an account; without it we cannot open one. We do not make decisions about you based solely on automated processing that have legal or similarly significant effects.

We do not sell your data, use advertising trackers or profile you for marketing.

5. How your files are protected

Files are encrypted at rest. Each folder has its own encryption key, which is derived from its access words and protected by a server-side key.

Skypost is not a zero-knowledge service. We run the encryption system, so authorised staff may be able to access files where this is necessary for legal compliance, investigating abuse, or security and technical support.

Large uploads (over about 50 MB) may be processed briefly before encryption is finalised. They are encrypted straight after processing and the temporary data is removed.

Anyone who has a folder’s access words or link can open it, so share them carefully. See our security page for more.

6. How long we keep data

DataHow long
Folders without an accountUntil the folder expires (see pricing for your plan). The files are then deleted.
Folders in an accountActive until they expire. They then move to your archive, which is kept for up to 12 months unless you revive or delete them sooner, and is then deleted.
Account dataUntil you delete your account. Deletion removes your folders, files, API keys and preferences straight away.
Deletion recordA single record that an account was deleted, holding a hashed email only, kept as evidence that we acted on the request.
Security and audit logsFor as long as needed for security, fraud prevention and legal claims. Logs linked to a deleted account are anonymised.
API usage logsUp to 90 days
Rate-limit recordsAbout 24 hours
Billing records6 years, as required by UK tax law
Enquiries and abuse reportsFor as long as needed to deal with them and any follow-up

Deleted data may stay in encrypted backups for a short period until those backups are overwritten.

7. Who we share data with

We use trusted service providers who process data on our behalf under written contracts:

ProviderWhat they do
CloudflareEncrypted file storage, content delivery and network security
Abacus.AIApplication hosting and database
StripePayments and subscriptions
ResendSending emails
TwilioSending SMS and WhatsApp messages
Browser push services (e.g. Google, Apple, Mozilla)Delivering push notifications, if you turn them on

We may also share data where the law requires it, to protect people from harm, or as part of a sale or restructuring of our business (in which case this policy would continue to apply). We do not sell or rent your data.

8. International transfers

Some of our providers process data outside the UK, including in the United States and the European Economic Area. When data leaves the UK we make sure it is protected by an adequacy decision (such as the UK Extension to the EU-US Data Privacy Framework, where the provider is certified) or by the UK International Data Transfer Agreement or the UK Addendum to the EU Standard Contractual Clauses. You can ask us for more detail.

9. Your rights

Under UK data protection law you have the right to:

  • Access the personal data we hold about you
  • Rectification: have inaccurate data corrected
  • Erasure: have your data deleted
  • Restriction: ask us to limit how we use your data
  • Portability: receive your data in a reusable format
  • Object to processing based on legitimate interests
  • Withdraw consent at any time, where we rely on consent

You can export your data and delete your account yourself from your account settings. For anything else, email [email protected]. We will reply within one month. This is free in most cases, and we may need to confirm your identity first.

10. Complaints

Please contact us first so we can try to put things right. You also have the right to complain to the Information Commissioner’s Office (ICO), the UK data protection regulator, at ico.org.uk or on 0303 123 1113.

11. Children

Skypost is not intended for children. You must be at least 16 to use it and 18 to buy a paid plan. If you think a child has given us personal data, contact us and we will delete it.

12. Cookies

We only use cookies and similar storage that are strictly necessary or that remember choices you make. See our Cookie Policy.

13. Changes to this policy

We may update this policy from time to time. We will change the “Last updated” date, and if a change is significant we will tell account holders by email or in the app before it takes effect.
