DATA PROCESSING AGREEMENT (DPA)
Last updated: April 23, 2026
1. How this DPA is accepted
This Data Processing Agreement ("DPA") forms part of the Terms & Conditions ("Terms") between you ("Clinic User", "Controller", "you") and Mathias Systems LLC ("Estetis", "Processor", "we", "us").
No separate signature is required. This DPA is automatically accepted and becomes binding when you:
Accept the Terms & Conditions, and
Activate a paid subscription to the Service.
By doing the above, you confirm that you are authorized to enter into this DPA on behalf of your business and that you accept all of its terms. If you do not agree, do not use the Service.
This DPA prevails over any conflicting terms in the main Terms & Conditions regarding the processing of End Customer personal data.
2. Background and purpose
You use the Estetis Service to run loyalty, rewards, and membership programs for your customers ("End Customers"). In doing so, you upload and process personal data about those End Customers through our platform.
Under applicable data protection laws — including the EU General Data Protection Regulation 2016/679 ("GDPR"), the UK GDPR, the Irish Data Protection Act 2018, and the Polish Act on the Protection of Personal Data — this makes you the Controller of End Customer personal data, and Estetis the Processor.
This DPA sets out the terms on which Estetis processes End Customer personal data on your behalf and satisfies the written contract requirement under Article 28(3) GDPR.
3. Definitions
Terms used in this DPA have the meanings given to them in the GDPR. In particular:
Personal Data — any information relating to an identified or identifiable natural person (here: End Customer data).
Processing — any operation performed on personal data.
Controller — the entity that determines the purposes and means of processing (you).
Processor — the entity that processes personal data on behalf of the Controller (Estetis).
Sub-processor — a third party engaged by the Processor to process personal data.
Data Subject — the individual to whom the personal data relates (End Customer).
Personal Data Breach — a breach of security leading to accidental or unlawful destruction, loss, alteration, unauthorized disclosure of, or access to, personal data.
Standard Contractual Clauses (SCCs) — the clauses adopted by the European Commission in Decision (EU) 2021/914 of 4 June 2021.
4. Details of processing
Subject matter: provision of the Estetis loyalty, rewards, and membership platform.
Duration: for as long as your subscription is active, plus any post-termination retention period agreed in the Terms.
Nature and purpose: storing, organizing, retrieving, using, and transmitting End Customer personal data to enable loyalty tracking, membership management, rewards redemption, push notifications, and communications initiated by you.
Types of personal data: first name, last name, email address, phone number, date of birth, loyalty and membership activity (points, rewards, transactions, timestamps), and other data you voluntarily upload within the permitted scope.
Categories of data subjects: your End Customers.
Full details are set out in Annex A.
5. Your obligations as Controller
You are solely responsible for:
Having a valid lawful basis under Article 6 GDPR for processing End Customer data (typically consent or legitimate interests for loyalty programs).
Providing End Customers with your own privacy notice that meets Articles 13 and 14 GDPR.
Obtaining any required consents — particularly for marketing communications, push notifications, and newsletters sent via the Service.
Not uploading special-category data (health data, biometric data, racial/ethnic origin, political opinions, religious beliefs, sexual orientation) or data relating to criminal convictions. This data is contractually excluded from the Service.
Ensuring that End Customer data is accurate and lawfully collected.
Responding to Data Subject requests concerning their rights (access, rectification, erasure, etc.).
Complying with all other applicable data protection, marketing, and consumer protection laws.
You will indemnify Estetis against any claim, fine, or liability arising from your failure to meet these obligations.
6. Our obligations as Processor
Estetis will:
6.1 Process on documented instructions
Process End Customer personal data only on your documented instructions, including instructions regarding transfers of personal data to a third country. Your instructions are considered documented through: (a) the Terms, (b) this DPA, (c) your configuration and use of the Service, and (d) any additional written instructions you provide.
If we believe an instruction violates data protection law, we will inform you. We may refuse to follow an instruction that is manifestly unlawful.
6.2 Confidentiality
Ensure that our personnel authorized to process End Customer data are bound by written confidentiality obligations or appropriate statutory confidentiality.
6.3 Security
Implement appropriate technical and organizational measures to protect End Customer personal data in accordance with Article 32 GDPR. Current security measures are described in Annex B.
6.4 Assist you
Taking into account the nature of the processing and the information available to us, provide reasonable assistance with:
Responding to Data Subject rights requests (Articles 15–22 GDPR)
Security, breach notification, and Data Protection Impact Assessments (Articles 32–36 GDPR)
Consultations with supervisory authorities
Assistance is provided via the Service's built-in tools where possible (e.g., data export, deletion features). Extensive manual assistance may be subject to reasonable fees.
6.5 Breach notification
Notify you without undue delay, and where feasible within 72 hours, after becoming aware of a Personal Data Breach affecting End Customer data. Our notification will include the information required under Article 33(3) GDPR to the extent known.
6.6 Return or deletion
At your choice, delete or return all End Customer personal data at the end of the provision of the Service, unless storage is required by law. Standard deletion occurs within 90 days of termination, as set out in our Privacy Policy.
6.7 Compliance and audit
Make available to you information necessary to demonstrate compliance with Article 28 GDPR, including responses to reasonable written due-diligence questionnaires. We will permit audits on reasonable prior written notice, no more than once per year, subject to confidentiality, at your expense, and scheduled to avoid disruption to the Service. A third-party audit report, certification, or completed security questionnaire will satisfy audit requests where reasonably sufficient.
7. Sub-processors

7.3 Changes
We will notify you by email or in-app notification at least 30 days before adding or replacing a sub-processor.

If we cannot reasonably accommodate your objection, you may terminate your subscription and receive a pro-rata refund for the unused prepaid period.
7.4 Liability for sub-processors
We remain liable to you for the acts and omissions of our sub-processors to the same extent as for our own acts and omissions.
