Legal basis: legitimate interest and compliance with legal security obligations.
4. Registrations and interactions through bots
Bytefish may allow interactions through bots or integrations with external platforms, such as WhatsApp, Telegram or equivalent services, for registration, authentication, competition registration, catch submission, operational notifications and support.
When the user interacts with these channels, identifiers associated with the respective platform may be processed, such as phone number, user identifier, profile name, messages sent, photographs, videos and other data required for the service to function.
These external platforms have their own privacy policies and terms of use, for which Bytefish is not responsible.
5. Competition organising entities
Bytefish may be used by competition organising entities, clubs, associations, federations, companies or other sporting event promoters.
When the user registers for or participates in a competition organised by a third-party entity, the data required to manage the competition may be made available to the respective organising entity, including registration data, sporting identification, team, submitted catches, results, classifications, operational contacts and data required for competition validation or monitoring.
The organising entity may also process personal data under its own responsibility, namely for competition management, communication with participants, awarding prizes, compliance with rules and legal obligations. In such cases, the organising entity must ensure compliance with its own legal obligations regarding data protection.
In some competitions, data, photographs, videos, results or validation information may be submitted by organising entities, marshals, judges or other authorised users within the scope of competition management, monitoring and validation.
6. Processors, hosting and technical providers
Bytefish uses service providers that may act as processors, processing personal data on behalf of Bytefish and in accordance with the instructions received.
Hosting provider: OVHcloud.
The platform data may be hosted on infrastructure located in the European Union, namely in data centres in France, when that location is configured for the service used.
Hosting data in France does not, in itself, constitute an international transfer outside the European Economic Area, since France and Portugal are subject to the GDPR.
Other technical providers may also be used for sending emails, messages, notifications, payment processing, storage, security, monitoring, technical analysis or operational support.
7. Data sharing
Bytefish only shares personal data when necessary to operate the platform, provide the service, manage competitions, comply with legal obligations, protect rights or with the data subject’s consent.
Data may be shared, where applicable, with:
- Competition organising entities;
- Judges, marshals, validators or authorised evaluation teams;
- Technical service and hosting providers;
- Communication services, such as email, WhatsApp, Telegram or equivalent services;
- Payment and billing providers, where applicable;
- Public, tax, judicial or administrative authorities, when legally required.
Where international transfers of data outside the European Economic Area occur, Bytefish will adopt the legally required safeguards, namely adequacy decisions, standard contractual clauses or other mechanisms provided for under the GDPR.
8. Public publication of sporting information
Certain information relating to competitions may be displayed publicly on the Bytefish platform or on associated pages, including rankings, classifications, participant names, team names, entities, catches, photographs, measurements, weights, scores and statistics.
This publication aims to ensure competition transparency, allow public monitoring of results, promote the sport and preserve the sporting history of competitions.
Where technically possible and legally applicable, the user may request the correction of incorrect data or submit a reasoned objection to the processing, under the terms of the GDPR.
9. Data retention
Personal data is retained only for the period necessary for the purposes for which it was collected, without prejudice to legal, tax, accounting, sporting or rights-defence retention periods.
In general terms:
- User account: while the account is active and for the period necessary to comply with legal obligations or defend rights;
- Registration data: for the period necessary for competition management, sporting history, billing, audit and any complaints;
- Results, rankings and classifications: for the sporting and historical life of the competition, unless a legally applicable justified objection is upheld;
- Photographs, videos and validation metadata: for the period necessary for validation, audit, fraud prevention, complaint management and preservation of the competition history;
- Billing and payment data: for the applicable legal tax and accounting periods;
- Technical and security logs: for a period proportionate to security, fraud prevention, technical diagnosis and service continuity needs;
- Support communications: for the period necessary to resolve the request and defend rights.
A request to delete an account may not imply the immediate deletion of all data associated with competitions already held, where retention is necessary to comply with legal obligations, defend rights, preserve the integrity of results, maintain sporting history, support audits, prevent fraud or ensure competition transparency.
10. Rights of data subjects
Under the GDPR, the data subject may exercise, where applicable, the following rights:
- Right of access to their personal data;
- Right to rectification of inaccurate or incomplete data;
- Right to erasure of data, where legally applicable;
- Right to restriction of processing;
- Right to object to processing;
- Right to data portability;
- Right to withdraw consent, where processing is based on consent.
Requests must be sent to privacidade@bytesandes.com.
A response will generally be provided within a maximum period of 1 month from receipt of the request. In complex cases, this period may be extended under the terms provided by law.
The data subject also has the right to lodge a complaint with the competent supervisory authority. In Portugal, the supervisory authority is the Portuguese Data Protection Authority (Comissão Nacional de Proteção de Dados — CNPD), available at www.cnpd.pt.
11. Minors
Bytefish may be used in competitions or events involving minors, depending on the competition rules and the organising entity.
Where the processing of minors’ data depends on consent in the context of information society services, the legal rules regarding minimum age apply and, where required, consent must be obtained from legal representatives.
Organising entities are responsible for ensuring that the participation of minors in their competitions complies with applicable rules, including parental or legal representative authorisations, where necessary.
12. Data security
Bytefish adopts appropriate technical and organisational measures to protect personal data against loss, misuse, unauthorised access, alteration, disclosure or destruction.
These measures may include, among others:
- Access control and permissions by user profile;
- Protection of credentials, tokens and private links;
- Recording and monitoring of actions relevant to security and validation;
- Fraud prevention measures and duplicate submission detection;
- Protection of multimedia content and metadata;
- Backups, technical maintenance and service continuity measures;
- Minimisation of access to data only to those who need it to operate the platform or the competition.
Despite the measures adopted, no IT system is completely immune to risk. Bytefish works continuously to improve platform security and reduce risks for users.
13. Personal data breach
In the event of a personal data breach, Bytefish will act without undue delay, analyse the incident, adopt containment and corrective measures, document the occurrence and make the legally required notifications to the supervisory authority and, where applicable, to the data subjects.
14. Cookies and similar technologies
The Bytefish platform uses cookies and similar technologies for functionality, security, authentication, preferences, measurement and improvement of the user experience.
Cookies strictly necessary for the functioning of the platform, authentication, security or provision of a service requested by the user may be used without prior consent.
Analytics, measurement, personalisation or marketing cookies will only be used where there is consent or another applicable legal basis, under the terms of the legislation in force.
The user may manage their cookie preferences through the tool made available on the platform, where applicable, or through their browser settings.
Where applicable, Bytefish may provide a separate Cookie Policy with more detailed information on the cookies used, their purposes, duration and ways to manage consent.
15. Links to third parties
The platform may contain links to websites, social networks, payment platforms, communication groups or external services. Bytefish is not responsible for the privacy policies, practices or content of such third parties.
Users are advised to consult the privacy policies of external services before using them.

Each competition may have its own rules defined by the respective organising entity. By registering for a competition, the user cumulatively accepts:
- these Terms and Conditions;
- the Bytefish Privacy Policy;
- the specific rules of the competition;
- the legitimate decisions of the organising entity, judges, marshals or authorised validators, within the scope of the competition.
The organising entity is responsible for the technical rules of the competition, validation criteria, tie-break criteria, schedules, fishing areas, valid species, limits, penalties, complaints, prize allocation and sporting decisions.
Bytefish provides the technological infrastructure supporting the management of the competition, without prejudice to being able to technically assist the organising entity in the configuration, validation, communication and operation of the event.
6. Submission of catches, photographs, videos and other content
By submitting photographs, videos, text, measurements, weights, location, technical data or metadata, including EXIF/GPS where applicable, the user declares that:

A catch may be rejected or corrected when the submission does not comply with the competition rules, does not allow adequate validation, shows signs of manipulation, is incomplete, contains inconsistent data or breaches these Terms and Conditions.
Complaints, reviews or correction requests relating to results and validations must follow the deadlines and procedures defined in the competition rules or by the organising entity.

The publication of these elements aims to ensure competition transparency, allow public monitoring of results, promote the sport and preserve the sporting history of competitions.
