1. Who operates Stacly
Stacly Sync ("Stacly," "we," "us") is operated by MAHALO ADS NEGOCIOS DIGITAIS LTDA, a company registered in Brazil under CNPJ 60.528.953/0001-59, with its registered address at R Santa Catarina, 45, Sala 1, Parque Residencial, Jacutinga/MG, CEP 37.590-000, Brazil. You can reach us at mahaloads@outlook.com.
2. Who can use Stacly
Stacly is intended for users who are at least 18 years old. By creating an account, you confirm that you are 18 or older. We do not knowingly offer Stacly to anyone younger, and we deliberately did not build any feature aimed at minors.
3. What Stacly is
Stacly is a personal supplement-tracking app. It helps you record the supplements you take, how much you have left, your dosing schedule, purchases, and reminders.
4. What Stacly is not
Stacly does not provide medical, nutritional, or pharmaceutical advice, diagnosis, or treatment. It does not read medical records or prescriptions, and it is not designed to process photos of people — only product labels and packaging. Nothing in the app substitutes for advice from a qualified healthcare professional. If you have a health question, ask a doctor or pharmacist, not Stacly.
5. Your account
You sign in with your Google account; Stacly does not have its own separate password system. You are responsible for keeping access to your Google account secure. If you believe your Stacly account has been accessed without authorization, stop using the app and review your Google account's security settings immediately.
6. Your data
Everything you enter — supplements, bottles, doses, purchases, notes, reminders — belongs to you. You can export a copy of it or permanently delete your account and its data at any time from the Privacy screen. See the Privacy Policy for what is collected, why, and for how long.
7. AI-assisted features
Scan Bottle sends a photo you choose to take of a product label to OpenAI's API to read it and prefill supplement details for you to review and correct. Ask Stacly sends the text of your question to Google's Gemini API to answer questions about how to use Stacly itself — it is not a source of medical or nutrition advice, and it is designed to say so if asked a question outside that scope. Both features only run when you actively use them; neither runs in the background.
8. Acceptable use
You agree to use Stacly only for its intended purpose, not to attempt to access another user's data, not to interfere with or disrupt the service, and not to use the app to store or submit content that is unlawful under the laws applicable to you.
9. Service availability
We aim to keep Stacly available and reliable, but like any online service it can experience downtime, bugs, or interruptions, including from our infrastructure providers. We do not guarantee uninterrupted or error-free operation.
10. Limitation of liability
To the maximum extent permitted by applicable law, Stacly and MAHALO ADS NEGOCIOS DIGITAIS LTDA are not liable for indirect, incidental, or consequential damages arising from your use of the app, including decisions you make about supplements based on information you yourself entered or that an AI-assisted feature helped you read from a label. This section does not limit any right that cannot be limited under the mandatory consumer-protection law applicable to you (see Section 12).
11. Changes to these Terms
If these Terms change in a way that requires your renewed acceptance, you will be asked to accept again before continuing to use the app. Your prior acceptance is kept as a record; it is never silently overwritten.
12. Governing law and your consumer rights
These Terms are governed by the laws of Brazil. If you are a consumer located in Brazil, nothing in these Terms limits the rights given to you by the Brazilian Consumer Protection Code (Código de Defesa do Consumidor), including your right to bring a claim in the courts of your own domicile. If mandatory consumer-protection law in your own country of residence gives you rights these Terms cannot override, that law applies to that extent.
