Privacy Policy

Last updated: 7 August 2026

TwigDo is a trading name of Sequel AI Ltd, a company registered in England and Wales under registered number 16897137, with registered address at 128 City Road, London, EC1V 2NX, United Kingdom ("we", "us"). Sequel AI Ltd is the data controller for the personal data described in this policy. The short version: the free app is local-first — your tasks live in your browser and are never sent to us.

1. Data that stays in your browser

When you use TwigDo without an account, all projects, tasks, notes, attachments and preferences are stored exclusively in your browser's local storage on the device you are using. We cannot see, access or recover this data.

Because that storage belongs to the browser rather than to us, the data is lost if you clear cookies and site data, browse in a private/incognito window, uninstall or reset the browser, or the browser evicts stored data to reclaim space. It is also specific to that browser: it does not appear in another browser, another profile, or on another device. We hold no copy, so we cannot restore it. Use the JSON export to keep your own backups, or enable cloud sync on a paid plan for a server-side copy.

2. Data we collect when you create an account

• Account data: your email address and optional profile details (name, avatar, company name/logo).
• Synced content: if you enable cloud sync (paid plans), your project trees are stored in our database so they can sync across your devices and to collaborators you explicitly invite.
• Billing data: payments are processed by our payment provider. We never see or store your full card details — only your plan status and customer reference.
• Usage data: privacy-respecting, aggregate analytics (no cross-site tracking, no advertising cookies).

3. Lawful bases for processing (UK GDPR)

• Contract — providing the Service you signed up for: account, sync, collaboration and billing.
• Legitimate interests — keeping the Service secure, preventing abuse, and understanding aggregate usage to improve it.
• Legal obligation — retaining billing and transaction records as required by tax and company law.
• Consent — optional extras such as marketing email; you can withdraw consent at any time.

4. What we never do

• Sell or rent your data to anyone.
• Use your tasks or projects to train AI models.
• Read your project content except where required to operate a feature you invoked (e.g. delivering it to a collaborator you invited).

5. Retention

Account and synced content is kept while your account is active. Deleting your account removes synced projects and profile data from our live systems within 30 days; backups roll off within a further 30 days. Billing records are retained for the period required by UK tax law (normally 6 years).

6. International transfers

Some of our service providers process data outside the UK. Where they do, transfers are protected by the UK International Data Transfer Agreement or the UK Addendum to EU Standard Contractual Clauses, or the provider's equivalent adequacy arrangements.

7. Sub-processors

We use a small number of trusted sub-processors to provide hosting, database and authentication, payment processing and transactional email. They process data only on our documented instructions and under appropriate confidentiality and security obligations. The current list is available on request from hello@twigdo.com.

8. Your rights

Under the UK GDPR you have the right to access, rectify, erase, restrict or object to processing of your personal data, and the right to data portability. To exercise any of these, email hello@twigdo.com — we respond within one month. You also have the right to lodge a complaint with the Information Commissioner's Office (ICO) at ico.org.uk.

9. Cookies & storage

We use browser local storage for app state and, when accounts are enabled, an authentication session cookie. No third-party advertising or tracking cookies are used.

10. Changes

If we change this policy we'll post the new version here and update the date above. Material changes will be announced by email to account holders.
