Welcome to Sivo ("we", "our", "us"). We respect your privacy and are committed to protecting your personal data. This Privacy Policy explains how we collect, use, store, and protect your information when you use the Sivo iOS application and related services (the "App").
By using Sivo, you agree to the practices described in this policy.
Sivo uses email forwarding to receive your emails. You set up a forwarding rule in your email account (university, work, or personal) to send copies to your unique Sivo receiving address. This means:
The following table outlines all data we collect, aligned with our App Store privacy disclosures:
| Data Type | What We Collect | Purpose |
|---|---|---|
| Email Address | The email address you use to register and log in | Account authentication |
| User Content | Emails you forward to Sivo (sender, subject, body, dates) | AI processing: classification, task extraction, summaries |
| AI-Generated Data | Summaries, extracted tasks, calendar events, classification results | Delivering core app features |
| Crash Data | Crash logs and error reports (collected by Sentry) | Diagnosing and fixing technical issues |
| Performance Data | App launch times, response times, basic usage metrics | Improving app stability and performance |
🚫 We do NOT collect: location data, advertising identifiers (IDFA), contacts, photos, browsing history, or any biometric data. We do NOT share data with any advertising or analytics networks.
We use the information we collect solely to:
We do not use your data for advertising, user profiling, behavioural tracking, or any purpose unrelated to delivering the Sivo service.
Sivo uses artificial intelligence to power its core features. This section explains exactly how your data is processed by AI and which providers are involved.
AI Providers we use:
We rely on two third-party AI providers, both accessed via their official commercial APIs:
| Provider | Used For | Data Sent |
|---|---|---|
| Anthropic (Claude API) | Automatic email classification, task extraction, deadline detection, and summarisation | Email content from emails you forward into Sivo (sender, subject, body) |
| OpenAI (GPT API) | The in-app AI chat assistant — only triggered when you actively send a message to the assistant | Your typed messages, and any email content you explicitly ask the assistant to analyse |
Important distinction between the two flows:
🔒 Zero Training Policy: Your data is NEVER used to train, fine-tune, or improve any AI models — neither ours nor the providers'. Both Anthropic's and OpenAI's commercial API terms explicitly prohibit the use of customer API data for model training. This is the default behaviour for paying API customers and does not require any opt-out from us or you.
Provider data handling:
We follow a clear, time-limited data retention policy:
📋 Your original forwarded emails are retained on Sivo's servers for 90 days, after which they are automatically and permanently deleted. Only the AI-generated summaries and extracted tasks are kept for as long as your account is active.
We are a productivity tool, not a data broker.
🚫 We will NEVER sell, rent, or trade your personal data to any third party.
We share data only with the following essential service providers required to operate the App:
| Service | Data Shared | Purpose |
|---|---|---|
| Anthropic (Claude API) | Forwarded email content | Automatic AI email classification, task extraction, summarisation |
| OpenAI (GPT API) | Your messages to the in-app AI chat assistant, plus any email content you explicitly ask the assistant to analyse | Powering the in-app AI chat assistant feature |
| Sentry | Crash logs, error reports (anonymous, not linked to identity) | Crash monitoring and bug fixing |
| Resend | Your email address only | Sending verification code emails |
| Cloudflare | Web traffic data | Website hosting, DNS, and email routing |
We may also disclose data if required by applicable law, regulation, or valid legal process.
You maintain full control over your data. You have the right to:
Sivo offers a free tier and a paid Pro subscription. All payments are processed exclusively through Apple's in-app purchase system.

The App is rated 17+ on the App Store and is not directed at children under the age of 17. We do not knowingly collect personal data from anyone under 17 years of age. If we become aware that we have inadvertently collected such data, we will take immediate steps to delete it.

By using Sivo, you consent to the transfer of your data to these locations. We ensure that appropriate safeguards are in place to protect your data in compliance with applicable laws.
We may update this Privacy Policy from time to time. When we make material changes, we will update the "Last Updated" date at the top of this page and notify you through the App or via email. Continued use of the App after any changes constitutes your acceptance of the updated policy.
