1. Who provides Dufit
Dufit is provided by DUOSIS SOLUCOES LTDA, Brazilian company registration (CNPJ) 62.626.322/0001-06, at Rua Professor Luiz Schwartz, 125, Apt. 502, Velha, Blumenau, SC, 89036-070, Brazil. For questions, requests or complaints, contact contato@duosis.com.br or visit support.
These Terms cover the Dufit app and website. Read them before creating an account or purchasing a subscription. The offer displayed by your app store at checkout and your statutory rights also apply. This English version is intended for users outside Brazil; it does not replace mandatory protections in your country or region.
2. Your account and access
Dufit is intended for people aged 18 or older. Provide accurate information, keep your contact details current and protect your credentials. Do not share your password or access another person's account or data without permission. Contact support if you suspect unauthorized access.
You may use Dufit as a personal trainer or a client, including in solo mode where available. Access to some features depends on your role, your connection to a trainer and your subscription. Features may also depend on your device, internet connection and regional availability.
3. Workouts, trainers and AI
Dufit helps users organize workouts, manage clients and record activities. It does not provide medical care or replace individual assessment, diagnosis, treatment or professional supervision.
Trainers are responsible for the instructions and content they provide, the suitability of workouts for their clients and any qualifications required where they practice. Arrangements for professional services between a trainer and a client are separate from a Dufit subscription. Using Dufit does not certify a trainer's qualifications.
Public workout libraries, solo mode and AI-generated suggestions provide general assistance and may contain errors or suggestions that are unsuitable for you. They are not medical prescriptions or guarantees of safety or results. Seek advice from a qualified professional, respect your limitations and stop if you experience pain or feel unwell. Solo mode requires acceptance of the specific notice shown in the app.
This information does not remove Dufit's legal responsibility for its own service.
4. Plans and subscriptions
The free plan for trainers supports one client. Paid plans may increase this limit and provide additional features. Solo AI features may be offered through a separate subscription. Review the in-app offer for the included features, limits and billing period before purchasing.
Subscriptions are purchased through Apple App Store or Google Play in-app purchases, with RevenueCat used to verify access. Dufit does not receive your full payment card details. The store displays the price, currency, billing period, applicable taxes and any promotional terms before you confirm. Visiting the website or creating a free account does not itself result in a charge.
Auto-renewing subscriptions are charged each billing period until canceled through the store where you subscribed. If a free trial or introductory discount is offered, review its duration and the price that follows. Plan and price changes are subject to the store's requirements and any notices or consent required by applicable law.
5. Cancellation, restoring purchases and refunds
Cancel renewal through the subscription settings of the Apple or Google account used to purchase. Cancel before the next renewal and follow the deadlines shown by your store. Access generally continues until the paid period ends; refunds, revoked purchases or specific offer terms may change that date.
Uninstalling Dufit or deleting your Dufit account does not cancel a store subscription. Cancel renewal separately to prevent further charges.
If a purchase is missing, use Restore Purchases in the app while signed in to the store account used for the purchase. If the issue continues, contact support with your order reference. Do not send passwords or payment card details.
Official store help is available here:
- Apple: manage or cancel a subscription and request a refund.
- Google Play: manage or cancel a subscription and request a refund.
Refund requests are assessed under store rules and applicable law. Those processes do not limit any mandatory cancellation, withdrawal, refund or other consumer rights you have. Dufit support can also help resolve service issues and direct your request appropriately.
6. Your content and acceptable use
You retain ownership of content you upload. You authorize Dufit to store, process and display it only as needed to operate the service, in accordance with your sharing permissions and our Privacy Policy. This permission does not transfer ownership of your content to Dufit.
Only upload material you have the right to use and share, and obtain necessary permissions for other people's images, information and data. Do not post unlawful or abusive content, infringe others' rights, bypass plan limits, compromise security, exploit vulnerabilities or collect other users' data without authorization.
Dufit's software, branding and materials are protected by intellectual property rights. Your access allows legitimate personal or professional use of the available features under these Terms and applicable licenses; it does not transfer ownership of the software or brand.
7. Privacy and account deletion
Our Privacy Policy (in Portuguese) explains the data we process, its purposes, necessary sharing and how to exercise your rights. Contact support for help understanding the policy. Respect the privacy of clients and others whose information you handle through Dufit.
You can request account deletion through the in-app feature or support. Deletion and any required record retention follow the Privacy Policy and applicable legal obligations. Cancel any active store subscription separately.
8. Availability and suspension
We work to keep Dufit available and correct faults. Maintenance, technical problems or third-party outages may interrupt service. We do not promise uninterrupted availability or particular fitness results.
We may restrict content or suspend access to address fraud, security risks, unlawful activity or violations of these Terms. Action should be proportionate, with an explanation and a way to contact support, unless disclosure is legally restricted or urgent protective action is necessary. Rights relating to amounts paid and defective services remain subject to applicable law.
If we discontinue a paid feature or the service, we will notify affected users and address the remaining paid period in accordance with their applicable rights. Nothing in these Terms excludes statutory warranties, remedies for defective services or liability that cannot lawfully be excluded or limited.
9. Store rules and the Apple license
Apple's or Google's terms also govern your store account, payment and app distribution. For the app obtained through the App Store, the Apple Standard End User License Agreement applies to the software license unless a custom license is provided in the store. These Terms supplement that license for Dufit's services without reducing mandatory rights.
10. Changes and local rights
We may update these Terms to reflect service or legal changes. We will publish the current version here with its revision date, provide reasonable advance notice of material changes and seek fresh consent where required. Updates do not remove accrued rights or authorize charges without the confirmation required by the store and applicable law.
Dufit is operated from Brazil. Any application of Brazilian law is subject to the mandatory protections you have where you live. For users in the United States, Canada, the United Kingdom and other countries, applicable federal, state, provincial or local consumer protections remain in force. These may include rights concerning subscriptions, refunds, privacy and access to competent courts or regulators. These Terms do not require arbitration, waive class-action rights or require you to bring claims exclusively in Brazil.
If a provision is unenforceable, the remaining provisions apply to the extent permitted by law. Contact contato@duosis.com.br with questions or to seek a resolution. Contacting support first is not a prerequisite to exercising your legal rights.
