Privacy policy
Last updated 2 November 2026
Splainer is a Windows app that listens when you ask, looks at your screen when you ask it to, and explains things out loud. This policy explains what happens to your data in each way you can run it. The short version: we store as little as possible, and nothing you say or show is kept on our servers.
Who is responsible
Splainer is made by Shadow Lancer in Sweden, which is the data controller for the Splainer website and Splainer Cloud. Contact us about privacy at enterprise@shadow-lancer.com.
What stays on your PC
- Your conversations, lessons, drawings and settings are saved on your computer only.
- API keys you paste in are encrypted with Windows (DPAPI) so only your Windows account can read them. They are never sent to us.
- Microphone audio is recorded only while you hold Ctrl + Alt or have hands-free talking switched on.
When data leaves your PC
You choose where each feature runs: chat, image understanding, speech recognition, spoken narration and voice conversations.
- Local: requests go only to servers on your own computer, such as Ollama, LM Studio or the voices built into Windows.
- Your own key: requests go directly from your PC to the service you picked, such as OpenAI, Google Gemini or Groq, under that service's own terms and privacy policy. We never see them. Some free tiers, including Google's, may use your data to improve their products.
- Splainer Cloud (when available): requests pass through our servers to the AI providers listed below so we can check your plan and count usage.
Screenshots are taken only when you ask about your screen or a task needs to see it, and they go only to the service chosen for image understanding. Browser and connected-account tools you enable may contact the websites and services involved.
What Splainer Cloud stores
| Data | Why | How long |
|---|---|---|
| Email address and sign-in identity (from Google or Microsoft) | To create and secure your account | Until you delete your account |
| Signed-in devices | So you can see and sign out devices | Until you delete your account |
| Usage counts: number of messages, tasks, voice minutes, model used, cost | To apply plan limits and prevent abuse | 13 months, then monthly totals only |
| Subscription and invoice records | Billing and accounting law | As required by Swedish bookkeeping law |
| Server logs without content (time, route, status) | Security and fixing errors | 30 days |
We do not store your prompts, replies, screenshots, audio or transcripts. They pass through our servers in memory on the way to the AI provider and back.
Service providers we use
- Supabase: accounts and usage database, hosted in Stockholm, Sweden.
- Google: Sign in with Google. We receive your name, email address and profile picture, nothing else.
- Cloudflare: hosts this website and protects it from attacks.
- AI providers for Splainer Cloud requests, such as OpenAI, Anthropic and Google. They process your request to produce an answer and may keep it for a limited time to detect abuse, under their API terms. They do not use API data to train models by default.
- Stripe: payments, when paid plans launch. We never see your full card details.
Some of these companies are based in the United States. Transfers rely on the EU–US Data Privacy Framework or the European Commission's Standard Contractual Clauses.
Legal basis
We process account and usage data to provide the service you signed up for (performance of a contract, GDPR article 6(1)(b)), and logs and abuse checks for our legitimate interest in keeping the service secure (article 6(1)(f)). Billing records are kept to meet legal obligations (article 6(1)(c)).
Your rights
You can ask for a copy of your data, have it corrected, have it deleted, restrict or object to processing, and take your data elsewhere. Deleting your account removes your profile, devices and usage records, except billing records the law requires us to keep. Email us and we will answer within one month. You can also complain to the Swedish Authority for Privacy Protection (IMY).
Children
Splainer Cloud is for people aged 13 and over.
