Privacy Policy

Last updated: April 26, 2026

This policy describes how Sojuki (the "App") handles your personal data when you use our services. We've written it to be clear: we want you to understand exactly what happens with your information.

1. Who is responsible

The data controller is Felipe Lechuga, a natural person based in Chile, operating Sojuki. For any privacy, data or rights inquiries, write to app@sojuki.com.

2. What data we collect

Only what's necessary for the App to work. Specifically:

2.1 Data you give us

2.2 Data the App generates automatically

2.3 Data we ask for only with your permission

3. How we use your data

What we don't do: we don't sell your data, don't use it for third-party advertising, and don't build profiles for external marketing.

4. Who we share your data with

We work with providers ("subprocessors") that help us run Sojuki. Each receives only the minimum information needed for their function:

ProviderFunctionData receivedLocation
ClerkAuthenticationEmail, name, hashed password or OAuth tokensUnited States
RailwayServer and database hostingAll App informationUnited States
Cloudflare R2Photo storageProfile and pet photosGlobal network (Cloudflare)
Anthropic (Claude API)AI message generationPet names, household data and routines (see section 5)United States
Open-MeteoWalk weatherApproximate coordinates (not stored)Europe
Expo (push)Push notification deliveryPush token + notification contentUnited States

Some of these providers process data outside Chile. International transfers are made under standard contractual clauses and/or recognized legal frameworks (Data Privacy Framework, SCC) as applicable.

5. Artificial intelligence

Sojuki uses Claude (by Anthropic) to generate content like weekly letters and daily messages "written by your pet". To do this, we send Anthropic a context that may include: your pet's name, household members' first names, completed or pending tasks from the last week, weather, and upcoming events (birthdays, vaccines).

We never send Anthropic: your email, your national ID, passwords, payment information, or the content of private notes you write.

Per its commercial terms, Anthropic does not use this context to train its models. More information in its privacy policy: anthropic.com/legal/privacy.

6. How long we keep your data

If the law requires us to retain something longer (e.g. tax information), we keep it only for the legally mandated period.

7. Your rights

Under Chile's Law 19,628 (Protection of Private Life) and Law 21,719 once in effect, and as a baseline for users elsewhere, you have the right to:

To exercise any of these rights, write to app@sojuki.com. We respond within 15 business days. If you live in the European Union, you can also contact your local data protection authority.

8. Children

Sojuki is not directed at children under 13. We don't knowingly collect data from children. If you discover that a minor under 13 created an account without parental authorization, write to us and we will delete it.

9. Security

We apply reasonable technical and organizational measures to protect your data: encrypted connections (HTTPS/TLS), hashed passwords, restricted server access, encrypted backups. No system is 100% invulnerable, but we take this responsibility seriously.

10. Changes to this policy

If we make material changes, we'll notify you via email and/or in the App at least 15 days before they take effect. Minor changes (corrections, clarifications) are published here with an updated date at the top.
