Privacy Policy

Last updated: 26 October 2026

This policy describes how we collect, use and share personal data when you use Hypersay: the websites hypersay.com, app.hypersay.com, slides.hypersay.com and live.hypersay.com (the "Service"). Please read it together with our Terms of Use.

Who is responsible for your data

Hypersay is operated by B-Side Tech Limited, a company registered in England and Wales (company number 15995448), registered office 1004 Lock Apartments, 21 Gillender Street, London, E3 3YH, United Kingdom. B-Side Tech Limited is the controller of the personal data described here. Hypersay was created by Learn Forward Ltd, which has passed the service and its data to B-Side Tech Limited.

For anything about your personal data, write to hello@hypersay.com, or use the data protection page in the dashboard.

What we collect and why

E-mail address: To identify you, sign you in with one-time codes and send you messages about your account and sessions. It is not shown to other users.
Name, nickname and profile picture: Shown to the people in the sessions you host or join, and next to your questions and answers where the session shows them. You can change them at any time.
Google account identifier: If you sign in with Google, so that we recognise you. We receive your name, e-mail address and picture from Google.
Sign-in token: Kept in your browser to keep you signed in, removed when you sign out.
Last IP address and sign-in dates: To protect accounts against misuse. Sign-in dates are kept for 30 days.
Language and preferences: To show the Service in your language and remember your settings.
Documents you upload: Converted into slide images and stored so that you can present them. They are visible to you and to anyone who joins your sessions or knows the session code. They are not public or indexed by search engines.
Interactive content you add: Questions, quizzes and other content you add to your presentations, under the same rules as the documents.
Your answers, questions, votes, chat messages, claps and feedback: Shared with the presenter, and with other participants where the session shows them. We keep a history of answers for the session's reports. Votes and claps are only shown as totals; feedback is shown to the presenter without your name.
Notes you take: Private to you.
Payment details: If you buy a plan or credits: what you bought and when. Card details go straight to Stripe and never reach our servers.
Usage data: Pages visited, device and browser type, to fix problems and improve the Service.

We do not collect special categories of personal data (such as health, ethnic origin, political or religious views), and we make no automated decisions about you.

Our legal bases

Contract: most of the data above is needed to provide the Service you asked for.
Legitimate interests: security, preventing misuse, and understanding how the Service is used so we can improve it.
Consent: for any marketing e-mails. You can withdraw consent at any time.
Legal obligation: keeping payment records as the law requires.

Who we share it with

We don't sell your personal data. We use these service providers to run Hypersay:

Fly.io: Servers running the Service, and storage of documents, slide images and uploaded files (Tigris). Location: United Kingdom (London) and other Fly.io regions.
MongoDB (Atlas): The database. Location: Ireland (EU).
Vercel: Hosting the websites, and cookie-free visitor statistics (Vercel Web Analytics), with no personal data. Location: Global network, United States company.
MailerSend: Sending sign-in codes, reports and notifications. Location: European Union.
Stripe: Payments. Location: United States and Ireland.
Google: Sign-in with Google. Location: United States and global.
tawk.to: The support chat on hypersay.com, if you use it. Location: United States.
Proton: Our company e-mail, if you write to us. Location: Switzerland.

We may also share data if the law requires it, to protect our rights or users' safety, or with a buyer if the Service is sold, in which case this policy continues to apply to your data.

Some providers process data outside the UK. Where they do, the transfer is covered by UK adequacy regulations or by standard contractual clauses.

How long we keep it

We keep your data while you use Hypersay. Presentations, uploaded documents and accounts that have not been used for two years are deleted, with everything they hold, from the database and from storage. Accounts with an active subscription are kept. Where a deleted account's participation is part of another presenter's session reports, the account is emptied instead: its e-mail, name, sign-ins and payment records are removed and only an anonymous record remains.

Payment records are kept as long as the law requires (usually six years).

You can ask us to delete your account and data at any time.

Cookies

We use cookies and browser storage to keep you signed in and remember your preferences; the Service does not work without them. We measure visits with Vercel Web Analytics, which sets no cookies. You can block cookies in your browser settings.

Security

Data is sent over encrypted connections (HTTPS) and stored with providers that protect it with technical and organisational measures. Access is limited to the people who run the Service. No system is completely secure, so we cannot guarantee the security of data sent over the internet.

Your rights

Under UK and EU data protection law you can:

ask for a copy of your personal data, also in a machine-readable format;
ask us to correct or delete it;
object to or ask us to restrict how we use it;
withdraw your consent where we rely on it.

Use the data protection page in the dashboard or write to hello@hypersay.com. We may need to confirm your identity first. We answer within one month and do not charge for it.

If you are unhappy with how we handle your data, you can complain to the Information Commissioner's Office (ico.org.uk) or the supervisory authority where you live. We would appreciate the chance to deal with your concern first.

Children

Hypersay is not meant for children under 16, and we do not knowingly collect their data.

Changes to this policy

We may update this policy as the Service or the law changes. The current version is always at hypersay.com/privacy, and we will tell account holders about material changes by e-mail or in the Service.
