List of subprocessors
SF-LABS sp. z o.o. processes the personal data of event attendees as a processor acting on behalf of organizers. To run the SF-CONFERENCE system we rely on further processors, known as subprocessors. The list below says who they are, why they receive data and which categories of data are involved.
Every subprocessor works under an agreement that guarantees a level of data protection no lower than the one set out in the Data processing agreement. Under its § 5 we announce every change to this list, and an organizer may raise a reasoned objection to a new subprocessor within 7 days of being notified.
§ 1. Subprocessors
Some of the entities below run core system functions, so their involvement does not depend on the settings of a single event. The rest receive data only once the organizer turns the related feature on, which we note next to every such purpose.
Some of these entities receive no data from the system database. Data reaches them because the visitor's browser downloads a resource straight from their servers, which reveals the IP address and device details.
DigitalOcean LLC
The provider of the server the whole system runs on.
- Purpose of processing
- Running the environment that hosts the application and the system database, the place where all processing of event data happens.
- Categories of data
- All data processed in the system, including attendee, entry, payment and invoice data as well as the content of event websites, because the database and the application run on that server.
- Location
- Germany, a data centre in Frankfurt. The provider is based in the United States, and the transfer relies on standard contractual clauses.
Amazon Web Services EMEA SARL
The cloud infrastructure provider the system sends mail and stores files through.
- Purpose of processing
- Delivering the messages sent from the system, meaning registration confirmations, entry tickets, certificates, invoices, reminders and mailings, and storing event files, generated documents and database backups.
- Categories of data
- E-mail address, first and last name, the message body and its attachments, files uploaded by organizers and attendees, and the documents the system generates, together with the personal data they carry.
- Location
- European Union, data centres in Ireland and Germany.
Google Cloud EMEA Limited
The cloud data warehouse provider the system keeps its technical logs in.
- Purpose of processing

- Location
- European Union, a data centre in Warsaw.
Google Ireland Limited
A provider of form protection, measurement tools and resources embedded in event websites.
- Purpose of processing
- Protecting forms against automated submissions by bots. On top of that, once the organizer turns those features on, measuring traffic on the event website and the performance of their advertising campaigns, and displaying embedded videos and fonts.
- Categories of data
- IP address, browser and device details, the way the form was filled in, identifiers stored in cookies and on-site behaviour.
- Location
- Ireland and the United States, under standard contractual clauses.
OpenAI Ireland Limited
The provider of the language models behind the assistant in the panel.
- Purpose of processing
- Carrying out the assistant instructions given by the organizer: creating and changing content, looking up information about the event and answering questions about the data in the panel.
- Categories of data
- The text of the instruction together with the event context, which depending on the question may cover attendee, entry, payment and invoice data. Requests are neither stored on the provider side nor used to train models.
- Location
- Ireland and the United States, under standard contractual clauses.
Stripe Payments Europe Limited, ING Bank Śląski S.A., PayU S.A., PayPro S.A.
Online payment operators. Data goes only to the operator the organizer connected to the event themselves.
- Purpose of processing
- Collecting the fees for taking part in the event and for extra options, and confirming the status of a transaction.
- Categories of data
- The payer's name or company name, e-mail address, amount, currency, payment title and transaction identifier. Card details go to the operator alone and never reach the system.
- Location
- Poland and Ireland. The operators act as separate data controllers.
Meta Platforms Ireland Limited, LinkedIn Ireland Unlimited Company
Advertising networks whose tags the organizer may add to their own tag container.
- Purpose of processing
- Measuring the performance of the organizer's advertising campaigns. The tags load only once the organizer adds them themselves.
- Categories of data

- Location
- Ireland and the United States, under standard contractual clauses.
Pexels GmbH
A free stock photo library with a search engine and image files.

§ 2. Other data recipients
The entities below are not subprocessors of SF-LABS, because they process data as separate controllers, under the law, or solely on the instruction of the organizer. We list them so the picture of the data flow is complete.
Public authorities and state registers
The national system of structured invoices run by the Ministry of Finance and the register of businesses run by Statistics Poland.
- Purpose of processing
- Issuing and submitting invoices in the form required by law, and filling in the company details on an invoice once a tax identification number is entered.
- Categories of data
- The full content of the invoice: the buyer's name and address, tax identification number, line items and amounts.
- Location
- Poland. The transfer follows from a statutory obligation, and the authorities act as separate data controllers.
Tools chosen by the organizer
The organizer's own mail server and the external systems they point the event notifications at.
- Purpose of processing
- Sending messages from the organizer's own address instead of the system address, and passing event activity on to their own tools, a CRM system for instance.
- Categories of data
- The recipient's e-mail address, the message body and its attachments, plus event data in the scope set in the notification configuration, including attendee data.
- Location
- Depends on the provider chosen by the organizer, who is responsible for that choice.
