Terms & Conditions

1. Service operator

Fitero is developed and operated by Hristo Lalev, an independent developer based in Sofia, Bulgaria. Questions may be sent to support@fitero.eu; the postal address for legal correspondence is listed in the Contact section at the end of this page.

In these terms, “Fitero,” “we,” “us,” and “our” refer to Hristo Lalev as the service operator. “You” means the person accessing or using Fitero.

2. Acceptance and changes

By downloading, creating an account for, purchasing through, or using Fitero, you agree to these Terms and Conditions and acknowledge the Privacy Policy. If you use Fitero on behalf of another person or organization, you confirm that you are authorized to accept these terms for them.

We may update these terms to reflect changes in Fitero, law, security requirements, service providers, or commercial arrangements. Material changes will be communicated through the app, website, or account email where appropriate. Continued use after the effective date of revised terms constitutes acceptance to the extent permitted by law.

3. Eligibility

You must be at least 16 years old to create a Fitero account or purchase a subscription. If the law where you live requires you to be older to enter this agreement independently, a parent or legal guardian must review and accept these terms for you.

You must be legally capable of entering a binding agreement and must not be prohibited from using the service under applicable law. Fitero may suspend an account where there is a reasonable basis to believe these eligibility requirements are not met.

4. Accounts and security

Fitero supports email-and-password accounts through Firebase Authentication. You must provide accurate information, keep access to your email and device secure, and promptly notify us at support@fitero.eu if you believe your account has been compromised.

You are responsible for activity carried out through your account unless caused by our failure to use reasonable security measures. You may not share authentication tokens, attempt to access another user’s data, or misrepresent your identity.

Some features work without an account. Cloud sync, account-based restore, and certain Pro functionality require a verified account and network access.

5. Licence and acceptable use

Subject to these terms, Fitero grants you a limited, personal, non-exclusive, non-transferable, revocable licence to install and use the app for lawful, non-commercial fitness tracking.

You may create workout records, exercises, templates, programs, targets, notes, and other training content for your own use. You retain rights in information you create. You grant Fitero only the limited permission necessary to store, synchronize, back up, process, and return that information when you request those services.

You must not:

• use Fitero unlawfully, fraudulently, or in a way that harms another person;
• attempt to bypass authentication, rate limits, storage limits, subscriptions, security measures, or feature restrictions;
• probe, attack, disrupt, overload, or introduce malicious code into the app or backend;
• access, collect, disclose, or interfere with another user’s information;
• reverse engineer, decompile, resell, sublicense, or commercially exploit Fitero except where applicable law expressly permits it;
• use Fitero or its content to infringe intellectual-property, privacy, or other rights.

6. Your data, offline use, and sync

Fitero is offline-first, and local device storage remains your responsibility. Device loss, damage, operating-system cleanup, uninstalling the app, or failing storage can remove local records that have not been backed up or synchronized.

Cloud sync is optional and requires an account. Sync attempts to preserve changes and keep each account’s records separated, but no synchronization or backup system can guarantee that data will never be delayed, duplicated, corrupted, or lost. Keep independent exports or backups for records that are important to you.

You may export supported data formats and may delete local and cloud training data through available controls. Account deletion is irreversible. Details are explained in the Privacy Policy.

7. Free features, trial, and Pro subscriptions

Fitero offers a Free plan and may offer a Pro subscription with additional features. The intended standard pricing is €2.99 per month or €19.99 per year, and eligible users may receive a 15-day free trial. Actual price, currency, taxes, trial eligibility, and available packages are shown in your app store before purchase and may vary by country or platform.

Purchases are processed by Apple App Store or Google Play with entitlement support from RevenueCat. We do not directly collect your payment-card details. By purchasing, you also agree to the relevant store’s billing terms.

Unless the store clearly states otherwise, subscriptions automatically renew until cancelled through your Apple or Google account settings. Deleting Fitero or your Fitero account does not itself cancel an app-store subscription. You must cancel through the store before the renewal deadline.

Refunds, billing disputes, and cancellation rights are administered by the store and applicable consumer law. Nothing in these terms removes a refund, withdrawal, conformity, or other right that cannot legally be excluded.

Features included in Free or Pro may evolve as Fitero develops. We will not retroactively charge you without authorization, and material adverse changes to an active paid service will be handled in accordance with applicable law and store requirements.

8. Health, exercise, and safety

Fitero is a fitness-recording and planning tool. It is not medical advice, diagnosis, treatment, physiotherapy, emergency guidance, or a substitute for a qualified healthcare or fitness professional.

Exercise carries inherent risks, including strain, injury, illness, disability, and, in rare cases, death. Before beginning or changing an exercise program, seek appropriate professional advice, particularly if you have a medical condition, injury, symptoms, are pregnant, take medication, or are unsure whether an activity is suitable.

You are responsible for selecting appropriate exercises, technique, equipment, weight, volume, intensity, rest, environment, and supervision. Stop exercising and seek qualified assistance if you feel pain, faintness, chest discomfort, unusual shortness of breath, or another concerning symptom. Do not rely on timers, estimates, charts, generated recommendations, or prior entries as guarantees of safe performance or results.

9. Privacy

Our processing of personal data is described in the Fitero Privacy Policy, which forms part of the service relationship. Please review it before creating an account or enabling cloud sync.

10. Availability, updates, and third-party services

We aim to keep Fitero available and reliable, but features may occasionally be unavailable due to maintenance, network conditions, app-store review, security incidents, provider outages, or technical problems. We do not guarantee uninterrupted or error-free operation.

Fitero may download or require updates for compatibility, security, legal compliance, or feature changes. Older versions may stop working with cloud services where continued support would create security or compatibility risk.

Firebase, RevenueCat, Apple, Google, hosting providers, device operating systems, and network operators are independent third parties. Their services are governed by their own terms, policies, and availability.

11. Intellectual property

Fitero’s software, name, app icon, interface, visual system, original text, artwork, databases, and related materials are owned by or licensed to the operator and are protected by applicable intellectual-property law. These terms do not transfer ownership to you.

You may not use the Fitero brand in a way that implies endorsement or affiliation without prior written permission. App-store screenshots and links may be shared for ordinary personal recommendation and review.

12. Suspension and termination

You may stop using Fitero at any time and may delete your account through available settings. We may restrict or suspend access where reasonably necessary to address security threats, unlawful use, material breach, harm to others, or legal obligations.

Where practical and lawful, we will provide notice and an opportunity to correct a remediable breach. Sections intended by their nature to survive termination—including intellectual property, disclaimers, liability, and governing law—remain effective.

13. Disclaimers

To the extent permitted by law, Fitero is provided “as is” and “as available.” We do not promise that the app will meet every requirement, produce a particular fitness outcome, calculate every value without error, or preserve every local record in all circumstances.

Nothing in this section excludes guarantees, remedies, or protections that apply to digital services and cannot be waived under consumer law.

14. Limitation of liability

Nothing in these terms excludes or limits liability for fraud, wilful misconduct, gross negligence, death or personal injury caused by negligence, breach of mandatory data-protection duties, or any liability that applicable law does not permit us to exclude.

Subject to the previous paragraph and to the fullest extent permitted by law, we are not liable for indirect or consequential loss, lost profits, lost opportunities, or loss of data arising from circumstances outside our reasonable control. For paid services, any aggregate contractual liability that may lawfully be limited will not exceed the amount you paid for Fitero during the twelve months preceding the event giving rise to the claim.

Your mandatory consumer rights remain unaffected.

15. Governing law and disputes

These terms are governed by the laws of Bulgaria, without depriving you of mandatory consumer protections available under the law of your habitual residence.

Please contact support@fitero.eu first so we can try to resolve a concern informally. If a dispute cannot be resolved, it may be brought before the competent Bulgarian courts or another court or consumer-dispute body available to you under mandatory law.

16. General provisions

If a provision of these terms is unlawful or unenforceable, it will be limited or removed only to the minimum extent necessary, and the remaining provisions will continue. Failure to enforce a provision immediately is not a waiver.

You may not transfer your account or these terms without our consent. We may transfer operation of Fitero together with appropriate notice and protections, including those described in the Privacy Policy.

These terms, the Privacy Policy, the purchase information shown before checkout, and any mandatory store terms form the agreement relating to your use of Fitero.
