Privacy Policy for Vial

This Privacy Policy explains how bitart, s.r.o. ("we", "us", "our") collects, uses, and protects your information when you use the Vial mobile application (the "App"). We are the data controller responsible for your personal data.

Vial is a personal tracking tool for logging GLP‑1 / peptide doses, weight, and related goals. Vial is not a medical device and does not provide medical advice. Please also see our in-app disclaimer.

1. A quick summary

• Most of the data you enter is stored on your device.
• If you create an account, we store your email and sync your tracked data to our secure cloud so it can be backed up and available across your devices.
• We use a small number of trusted service providers (Supabase, Adapty, Apple) to provide accounts, subscriptions, and basic app analytics.
• We do not sell your data, and we do not use it for third-party advertising.
• You can delete your account and associated data at any time from within the App.

2. Information we collect

Account information

When you sign up or sign in, we collect:

• Your email address and authentication credentials, or
• If you use Sign in with Apple, the identifier Apple provides (and, if you choose, your name and a real or Apple-relayed "Hide My Email" address).

Health and tracking data you enter

Data you choose to log in the App, such as:

• Peptides/medications, doses, dose units, schedules, and injection sites,
• Body weight entries and goals,
• Notes and reminders.

This may constitute health-related information. We process it only to provide the App's core features (tracking, reminders, charts, history). We treat it as sensitive and protect it accordingly.

Purchase and subscription data

When you start a free trial or subscribe, our payments analytics provider (Adapty) and Apple process information such as your subscription status, product identifiers, transaction identifiers, and anonymized device/usage signals needed to validate and manage your subscription. We never receive or store your full payment card details. Payments are handled entirely by Apple.

Diagnostics and usage data

We rely on Apple's App Analytics, which provides us with aggregated and anonymized statistics (downloads, sessions, retention, crashes) only from users who have opted in to share analytics with developers in their device settings. This data is not linked to your identity.

Technical data

Our service providers may process limited technical data (e.g., IP address, device type, app version, timestamps) as a necessary part of delivering the service and keeping it secure.

We do not use third-party advertising SDKs, and we do not track you across other companies' apps or websites.

3. How we use your information

• Provide and operate the App (store your logs, sync across devices, send the reminders you set),
• Create and manage your account and authenticate you,
• Process and manage your subscription and free trial,
• Maintain security, prevent abuse, and debug/fix problems,
• Understand aggregate usage to improve the App,
• Comply with our legal obligations.

4. Legal bases for processing (GDPR)

If you are in the European Economic Area / UK, we rely on the following legal bases:

• Performance of a contract - to provide the App and your account/subscription.
• Your explicit consent - for processing the health-related data you choose to enter (Article 9 GDPR). You can withdraw consent at any time by deleting that data or your account.
• Legitimate interests - to keep the App secure, prevent fraud, and improve the product, balanced against your rights.
• Legal obligation - where we must retain certain records (e.g., for tax/finance).

5. How your information is shared

We share data only with the service providers ("sub-processors") that make the App work:

These providers process data on our behalf under agreements that require appropriate safeguards. We may also disclose information if required by law or to protect our rights, users, or the public.

We do not sell your personal data.

6. International data transfers

Some of our service providers may process data on servers located outside your country, including in the United States. Where data is transferred outside the EEA/UK, we rely on appropriate safeguards such as the European Commission's Standard Contractual Clauses.

7. Data retention

• Account and tracked data: kept while your account is active. When you delete your account, your account and associated synced data are deleted from our systems (see Section 9).
• On-device data: removed when you delete the App or clear data within it.
• Purchase records: retained as long as required for legal, tax, and accounting purposes.

8. Security

We use industry-standard measures to protect your data, including encryption in transit (HTTPS/TLS) and access controls so that your synced data is accessible only to your account. No method of transmission or storage is 100% secure, but we work to protect your information and continually improve our safeguards.

9. Your rights and choices

Depending on your location, you may have the right to:

• Access the personal data we hold about you,
• Correct inaccurate data,
• Delete your data ("right to be forgotten"),
• Restrict or object to certain processing,
• Data portability,
• Withdraw consent at any time.

Deleting your account: You can delete your account and its synced data directly in the App at Settings → Delete account. This permanently removes your account and associated cloud data.

To exercise any other right, contact us at the email above. You also have the right to lodge a complaint with your local data protection authority (in Slovakia, the Úrad na ochranu osobných údajov SR).

10. Children's privacy

Vial is not intended for children. The App is rated for users 17+ and you must meet the minimum age required in your country to use it. We do not knowingly collect personal data from children. If you believe a child has provided us data, contact us and we will delete it.

11. Health information disclaimer

Vial is a personal logging tool, not a medical device, and does not provide medical advice, diagnosis, treatment, or dosing recommendations. The data you enter is for your own tracking purposes. Always consult a qualified healthcare professional regarding any medication or health decision.

12. Changes to this policy

We may update this Privacy Policy from time to time. We will revise the "Last updated" date above and, where appropriate, notify you in the App. Your continued use of the App after changes take effect constitutes acceptance of the updated policy.
