Terms of Use
Last updated: November 2026
This is a translation of the Portuguese original. If the versions differ, the Portuguese version prevails. See the Portuguese original
1. Acceptance of the Terms
By accessing and using DiaVida, operated by Diavida LTDA. (CNPJ 65.512.351/0001-27), you agree to these Terms of Use and to the Privacy Policy. If you do not agree with any part of them, do not use the service.
2. What DiaVida is
DiaVida is a free self-care app for people living with diabetes and for those who care for them. It logs blood sugar, meals, medications, physical activity and measurements, shows trends, sends reminders, creates a PDF report to take to any health professional, offers educational content and lets trusted people invited by the user follow along. DiaVida does not provide medical care, does not diagnose or prescribe, and does not replace appointments with health professionals. The ongoing medical care service (DiaVida+) is contracted separately, under its own terms presented at sign-up.
3. Use without an account, and optional accounts
The app can be used without an account: in that case, entries are stored only on the device and are the user’s responsibility (losing, replacing or resetting the device erases the data). Creating an account is optional and lets you save your entries, access them on another device and invite trusted people to follow along. When you create an account, provide truthful information, keep your login confidential and let us know if you suspect unauthorized use.
4. Health information
Information available in the app, on the website and on the blog is for guidance and educational purposes. DiaVida is not an emergency service. In an emergency, go to the nearest health service or call SAMU (192, in Brazil) or your local emergency number (911 in the US). No content replaces care from your doctor.
5. Free use and DiaVida+
The DiaVida app is free and requires no credit card or payment. DiaVida+ is an optional subscription service: its conditions are set out in separate terms, accepted at sign-up, and subscribing takes place outside the mobile app. Joining the waitlist, when it is open, only serves to receive updates and creates no charge or obligation.
6. Communications
Anyone who creates an account or joins the waitlist authorizes Diavida LTDA. to send service-related communications — operational notices (reminders, app notices), educational content, news and information about DiaVida+ — by email, device notification and, when provided, phone or WhatsApp. You can opt out of marketing communications at any time. Strictly operational communications continue while the account is active.
7. Intellectual property
DiaVida’s text, images, videos, design and code are owned by Diavida LTDA. or licensed for exclusive use in the service. Reproduction, distribution or modification without prior written permission is prohibited. Blog articles may be quoted with a link to the source.
8. User conduct
You agree not to: (a) use the service for unlawful purposes or in ways that violate the rights of others; (b) attempt to access other people’s accounts, systems or data without authorization; (c) reverse engineer, decompile or interfere with the technical operation of the service; (d) share login credentials.
9. Account closure
You can delete your account at any time in the app itself (Perfil → Excluir conta, that is, Profile → Delete account) or on the account deletion page (in Portuguese). Diavida LTDA. may suspend or close accounts that violate these terms, with prior notice when possible.
10. Limitation of liability
Diavida LTDA. makes reasonable efforts to keep the service available, secure and working, but does not guarantee uninterrupted availability. It is not liable for indirect damages or for consequences of using, or being unable to use, the service, except as provided by law.
11. Changes
These Terms may be updated. Material changes will be communicated through the contact channels on file at least 15 days in advance. Continued use after publication constitutes acceptance.
12. Contact
Questions, suggestions or requests: suporte@diavida.com.br or through the Support menu in the app.
13. Jurisdiction
Any disputes arising from these terms shall be settled in the courts of the judicial district where the company is headquartered.
