Privacy Policy

Version: 1.0 Last updated: March 12, 2026 Operator: bivy

Note: This English version is provided for convenience. In the event of any discrepancy between the German and English versions, the German version (Datenschutzerklärung) shall prevail.


1. Data Controller

The controller within the meaning of the Swiss Federal Act on Data Protection (FADP, SR 235.1) and the EU General Data Protection Regulation (GDPR, Regulation (EU) 2016/679) is:

bivy Switzerland

UID: in formation Email: datenschutz@bivy.ch

1.1 Data Protection Officer (if appointed)

Email: datenschutz@bivy.ch

1.2 EU Representative (Art. 27 GDPR)

Where bivy processes personal data of individuals in the European Economic Area (EEA) and does not maintain an establishment there, the following representative is designated pursuant to Art. 27 GDPR:

To be designated upon completion of company formation.

Note: The exemption from the obligation to designate an EU representative (Art. 27(2) GDPR) requires cumulatively that (1) processing is only occasional, (2) there is no large-scale processing of special categories of data, and (3) the processing is unlikely to result in a risk to the rights and freedoms of natural persons. Since bivy is a SaaS platform that systematically serves users in the EEA, the designation of an EU representative is likely required.


2. Scope of This Policy

This privacy policy applies to the use of the website bivy.ch and the SaaS platform bivy offered thereon (the "Platform"). bivy is a digital construction project cockpit for private builders in Switzerland and the EU.

This policy explains what personal data we collect, for what purposes, on what legal basis, and for how long we process it. It also describes your rights and how you can exercise them.

In this policy, we use the terms "processing" (GDPR) and "Bearbeitung" (Swiss FADP) interchangeably to refer to any operation performed on personal data.

This Privacy Policy fulfils the information obligations under Art. 19 of the Swiss Federal Act on Data Protection (FADP, SR 235.1) and Art. 13 and 14 of the General Data Protection Regulation (GDPR).


3. Legal Basis for Processing

We process personal data on the following legal bases:

Legal Basis FADP (Switzerland) GDPR (EU) Description

4a.3 Legal Basis

bivy processes this data as a Processor on behalf of the User (Controller) pursuant to Art. 28 GDPR and Art. 9 FADP.

The legal basis for processing by the Controller (User) is:

  • GDPR: Art. 6(1)(f) (legitimate interest) — the Controller's legitimate interest in the efficient management of their construction project
  • FADP: Art. 31(1) (justification ground) — overriding legitimate interest in project management

4a.4 User's Information Obligation

The obligation to inform affected third parties lies with the User as Controller (Art. 14 GDPR / Art. 19(2) FADP). The User is required to inform their contacts (contractors, tradespeople, etc.) that their data is being processed via bivy, including AI-powered processing (see Section 6).

bivy provides the User with a template clause for construction contracts for this purpose, available in the Data Processing Agreement (DPA) at bivy.ch/avv.

4a.5 Purpose Limitation

Third-party data is processed exclusively for construction project management and AI-assisted task extraction. No disclosure to other users or third parties takes place (except for the sub-processors listed in Section 8).

4a.6 Retention and Deletion

Third-party data is linked to the project lifecycle. It is deleted:

  • when the User deletes the relevant project;
  • when the User deletes their account;
  • upon request of the affected third party (provided no statutory retention obligation applies).

4a.7 Rights of Affected Third Parties

Third parties whose data is processed via bivy may also exercise their rights (access, rectification, erasure, objection) directly with bivy. Please direct requests to:

Email: datenschutz@bivy.ch

In such cases, bivy will inform the relevant User (Controller) and cooperate with them to process the request.

7.2 No Tracking or Analytics Cookies

bivy currently uses no tracking or analytics cookies. In particular, we do not use Google Analytics or comparable services that transfer data to third countries. Should an analytics service be introduced in the future, we will use only GDPR-compliant solutions (e.g., Plausible Analytics) that operate without cookies and do not process personal data outside the EU.

7.3 Cookie Consent

Before setting any non-essential cookies, we obtain your explicit consent. You may withdraw your consent at any time by adjusting the cookie settings on our website or by deleting cookies in your browser.


8. Data Recipients and Sub-Processors

We share personal data with third parties only where necessary for the provision of our service, where you have consented, or where we are legally required to do so. All our sub-processors are subject to data processing agreements (DPAs) in accordance with Art. 28 GDPR and Art. 9 FADP.

9. International Data Transfers

9.1 Principle: All Data Remains in the EU

All personal data is processed and stored exclusively within the European Union or the European Economic Area. Our entire technical infrastructure is located in EU data centres (Frankfurt, Stockholm, Ireland).

9.2 Switzerland as an Adequate Third Country

The European Commission has recognised Switzerland as a country with an adequate level of data protection (adequacy decision pursuant to Art. 45 GDPR). Data transfers between the EU and Switzerland are therefore permitted without additional safeguards.

9.3 No Transfers to Inadequate Third Countries

We do not transfer personal data to countries outside the EU/EEA that do not have an adequacy decision. Should this change in the future, we will inform you and ensure the legally required safeguards are in place (e.g., Standard Contractual Clauses pursuant to Art. 46(2)(c) GDPR, Binding Corporate Rules, or your explicit consent).


10. Data Retention

We retain personal data only for as long as necessary for the respective processing purpose or as required by statutory retention obligations.

Data Category Retention Period Basis
Account data Until you delete your account; thereafter up to 30 days for complete deletion Contractual purpose
Project data Until you delete your account or manually delete the data Contractual purpose
Email data As long as the associated project exists; at the latest upon account deletion Contractual purpose
AI interaction data No persistent storage at AWS Bedrock; results stored as part of project data Contractual purpose
Payment data 10 years after the relevant financial year Art. 958f Swiss Code of Obligations (commercial retention obligation)
Technical data (server logs) Maximum 14 days Legitimate interest (operational security)
Cookie consent data 1 year (re-consent cycle: you are re-prompted after expiry; the localStorage entry persists until manually cleared or the cycle expires) Accountability obligation

Upon expiry of the applicable retention period, personal data is deleted or effectively anonymised. Statutory retention obligations (in particular commercial and tax law requirements) take precedence.


11. Your Rights as a Data Subject

Under the Swiss FADP and the EU GDPR, you have the following rights. We will respond to your requests within 30 days (Art. 25(7) FADP) or one month (Art. 12(3) GDPR) as a general rule. For particularly complex requests, this period may be extended; we will inform you in advance if this is the case.

11.1 Right of Access (Art. 25 FADP / Art. 15 GDPR)

You have the right to request information about whether and which personal data we process about you. We will provide you with a copy of the personal data being processed.

11.2 Right to Rectification (Art. 32(1) FADP / Art. 16 GDPR)

You have the right to request the correction of inaccurate personal data concerning you, as well as the completion of incomplete data.

11.3 Right to Erasure (Art. 32(2)(c) FADP / Art. 17 GDPR)

You have the right to request the deletion of your personal data, provided no statutory retention obligation exists and no overriding interest in continued processing applies.

11.4 Right to Restriction of Processing (Art. 18 GDPR)

Under the GDPR, you have the right to request the restriction of processing of your personal data, for example if you contest the accuracy of the data or if the processing is unlawful.

11.5 Right to Data Portability (Art. 28 FADP / Art. 20 GDPR)

You have the right to receive your personal data that you have provided to us in a commonly used, machine-readable format and to transmit that data to another controller.

11.6 Right to Object (Art. 21 GDPR)

Where we process data on the basis of a legitimate interest (Art. 6(1)(f) GDPR), you have the right to object to the processing at any time. We will then cease processing the data unless there are compelling legitimate grounds.

11.7 Right to Withdraw Consent (Art. 7(3) GDPR / Art. 6(7) FADP)

Where processing is based on your consent, you may withdraw it at any time with effect for the future. The lawfulness of the processing carried out prior to withdrawal remains unaffected.

11.8 Right to Surrender or Destruction (Art. 32(2) FADP)

Under Swiss law, you may request the surrender or destruction of your personal data.

11.9 How to Exercise Your Rights

Please address your requests to:

Email: datenschutz@bivy.ch Post: bivy, Switzerland

We must verify your identity before processing your request. Please have a copy of a valid identity document available.

Exercising your rights is generally free of charge. In the case of manifestly unfounded or excessive requests, we may charge a reasonable fee or refuse to process the request (Art. 25(6) and (7) FADP; Art. 12(5) GDPR).


12. Automated Individual Decision-Making and Profiling

12.1 Automated Individual Decision-Making (Art. 21 FADP / Art. 22 GDPR)

bivy does not make automated individual decisions that produce legal effects concerning you or similarly significantly affect you. Accordingly, neither the information obligation under Art. 21 FADP nor the restrictions under Art. 22 GDPR apply. Our AI features serve exclusively as decision support tools (see Section 6).

Should we introduce automated individual decision-making in the future, we will inform you in advance and grant you the right to express your point of view and to have the decision reviewed by a natural person.

12.2 Profiling

bivy does not carry out profiling within the meaning of Art. 5(f) FADP or Art. 4(4) GDPR that leads to an automated assessment of personal aspects of natural persons. We do not analyse your usage behaviour to make predictions about personal preferences, behaviour, reliability, or other personal aspects.


13. Data Security

We implement appropriate technical and organisational measures to protect your personal data against unauthorised access, loss, misuse, or destruction (Art. 8 FADP; Art. 32 GDPR). These include, in particular:

13.1 Technical Measures

  • Encryption in transit: All data transmissions are conducted exclusively via TLS 1.2 or higher (HTTPS).
  • Encryption at rest: All stored data is encrypted server-side (AWS KMS / Supabase encryption).
  • Access control: Access to production systems is strictly limited to authorised personnel and requires multi-factor authentication.
  • Row-Level Security (RLS): Database access controls ensure that users can only access their own data (multi-tenant isolation).
  • Passwords: Passwords are stored exclusively as cryptographic hashes (bcrypt). We never have access to plaintext passwords.
  • Regular security audits: Dependencies are automatically scanned for known vulnerabilities.

13.2 Organisational Measures

  • Principle of least privilege for all system access
  • Privacy by Design and Privacy by Default
  • Regular data protection and information security awareness training for staff
  • Documented procedures for handling data breaches

14. Data Breach Notification

In the event of a personal data breach, different notification thresholds apply under Swiss and EU law:

14.1 Notification to Supervisory Authorities

  • Switzerland (Art. 24(1) FADP): We notify the FDPIC as soon as possible where a breach is likely to result in a high risk to the personality or fundamental rights of data subjects.
  • EU (Art. 33 GDPR): We notify the competent supervisory authority within 72 hours of becoming aware of a breach where it is likely to result in a risk to the rights and freedoms of natural persons (a lower threshold than under Swiss law).

14.2 Notification to Data Subjects

  • Switzerland (Art. 24(3) FADP): We notify you where necessary for your protection or where the FDPIC so requires. A high risk to your personality or fundamental rights must exist.
  • EU (Art. 34 GDPR): We notify you without undue delay where the breach is likely to result in a high risk to your rights and freedoms.

15. Children's Data

bivy is intended for adult private builders. The Platform is not intended for persons under 16 years of age. We do not knowingly collect personal data from children under 16.

If we become aware that we have collected personal data from a person under 16, we will delete it without delay. If you have reason to believe that a child under 16 has submitted personal data to us, please contact us at datenschutz@bivy.ch.


16. Changes to This Privacy Policy

We reserve the right to amend this privacy policy at any time to reflect changes in legal requirements or our services. The current version is always available on our website at [bivy.ch/privacy].

For material changes that significantly affect your rights or the processing of your data, we will inform you before the changes take effect by appropriate means (e.g., by email or through a notice on the Platform).

The version published at the time you access the website or use the Platform shall apply.
