Legal
What personal data is processed, on what legal basis, where it is hosted and what you can do about it. With one distinction that changes everything in a service like this: when Blastack decides about data, and when it merely holds it on behalf of a customer company.

This English text is a courtesy translation of the Spanish original, provided so that the document can be read in English. In the event of any discrepancy between the two versions, the Spanish version prevails and is the only one with legal effect. The Spanish original is published at blastack.com/es/privacidad.
In an internal communications platform, the same company processes personal data in two positions that Regulation (EU) 2016/679 (GDPR) distinguishes clearly, and with different obligations. Telling them apart is the first thing to understand about this document.
The practical consequence is simple: if you are an employee of a company that uses Blastack, the controller of your data is your employer, not us. The section on rights explains who to approach and what we do if you write to us.
Any question about data protection, including the exercise of your rights, can be raised at info@blastack.com or in writing to the address given above.
These are the processing activities that we decide on, with their purpose, their legal basis and their retention period.
Browsing data: IP address, date and time, page requested, response code and browser type, collected in the web server logs.
Contact details you give us when you write to us: name, email address, company, job title and the content of the message.
Account sign-up data: first name and surname, email address, company name and the password, which is not stored as such but as a cryptographic derivative.
Data of the customer company's contact people: name, job title, email address and telephone number.
Billing data: registered company name, tax ID, registered tax address, payment details and monthly usage of the service.
Customers' email addresses for communications about the service itself: version changes, maintenance notices and product news.
We do not carry out profiling and we do not take automated decisions that produce legal effects concerning individuals or similarly significantly affect them.
When a company signs up for Blastack, it adds data about its own workforce to the platform. That data still belongs to the customer company, which is the controller. We host it and process it on its behalf. Depending on the features the company decides to use, it may include:
We do not use any of this data for our own purposes: not for advertising, not for profiling, not for training automated systems, and we do not disclose it to anyone. It is only accessed where this is strictly necessary in order to provide support or resolve an incident, and those accesses are logged.
When the customer company marks a survey as anonymous, the answer is stored with no link to the person who submitted it. This is not a promise made by the screen: the record of who answered what never comes into existence in the database, so neither an administrator at the company nor we can reconstruct it.
It is for the customer company to decide what data it adds, to have a legal basis for processing it, to inform its workforce in the terms of Articles 13 and 14 of the GDPR, and to comply with any applicable employment law, including consulting the employees' legal representatives where appropriate.
The relationship between the customer company, as controller, and Blastack, as processor, is documented in a data processing agreement under Article 28 of the GDPR, which forms part of the Terms of service and is accepted on signing up. It can be provided signed separately at the customer's request. Under that agreement we undertake to:
The service is provided from our own servers located in the European Union, in a data centre in France operated by Hostinger International Limited. Backups remain in the same jurisdiction.
No international transfers of data outside the European Economic Area take place. Neither the hosting, nor the backups, nor support, nor administration work are provided from outside the EEA, so there is no need to rely on standard contractual clauses or on other safeguards under Chapter V of the GDPR.
Files uploaded to the platform are stored on the server's own disk, in a folder per company, and are not reachable by direct address: every download checks the session and company membership again. The database is only accessible from the server itself and is not exposed to the internet.
The typefaces and the other resources on the site are served from our own server. When a blastack.com page loads, the browser makes no request to any third party, so no third party receives your IP address simply because you visited us.
We do not disclose personal data to third parties. It is only communicated where there is a legal obligation — to the tax authorities, to law enforcement or to the courts — or where it is necessary in order to bring or defend legal claims.
We do not use web analytics, advertising or campaign management services, or social media plugins, so none of those companies receives data about the people who visit the site or use the platform.
As controller, we keep each category of data for the period stated in its entry in section 3. Once that period ends, the data is blocked — kept but not used — for as long as legal liabilities may remain, and is erased afterwards.
As processor, we keep the platform data for as long as the contract with the customer company is in force. When it ends, the company has 30 calendar days in which to export its information. After that period, the data and the files are permanently erased within a maximum of 30 further days, including backups, apart from anything we are required to keep by law, which is limited to billing data.
Trial accounts that do not lead to a contract are closed at the end of the 15 days and their data is deleted on the same basis.
We apply technical and organisational measures appropriate to the risk, in accordance with Article 32 of the GDPR. Among others:
The detail of how this is built, including what we do not offer yet, is on the security page.
The GDPR gives individuals the following rights over their data:
To exercise them, simply write to info@blastack.com or to the address given in section 2, stating which right you are exercising and enclosing a copy of a document that proves your identity. We will reply within one month, extendable by a further two months if the request is particularly complex, in which case we will tell you. Exercising these rights is free of charge.
If you are an employee of a company that uses Blastack and your request concerns the data held on the platform, the one who has to deal with you is your employer, because it is the controller. If you write to us we will tell you so, and we will pass the request on to your employer without delay, so that it does not get lost along the way.
If you consider that we have not dealt with your request properly, you can lodge a complaint with the Spanish Data Protection Agency (Agencia Española de Protección de Datos, C/ Jorge Juan, 6, 28001 Madrid, www.aepd.es). You do not have to complain to us first, although we appreciate the chance to put it right ourselves.
The service is aimed at companies and at the people who work in them. It is not intended for children under 16 and we do not deliberately collect their data. If a customer company adds data about people under that age, it is that company which must have the appropriate legal basis.
This policy may be updated because of changes in the law, recommendations from supervisory authorities or how the service develops. The version in force is always the one published on this page, with the update date shown at the top.
Where the change is substantial, customers will be notified by email or within the platform a reasonable time before it takes effect.
If anything above is unclear, or your legal department needs the text signed or in another format, email us at info@blastack.com. We answer in writing.
