Privacy Policy
Last updated: September 26, 2026 · Deutsche Version · Legal Notice (Impressum)
1. What We Collect
VoltType collects the minimum data necessary to provide the service:
- Account information: Email address when you create an account. If you sign in with Google, Google sends us your email address, name and profile picture so we can create and identify your account; we request nothing else from your Google account and never post or read anything on your behalf.
- Audio data: Your voice recordings are sent to our servers for transcription only. Audio is processed in real-time and never stored on our servers.
- Usage data: We track the number of seconds and words transcribed per day for billing and plan limits, and which app and version made the request. We do not store the content of your transcriptions on our servers.
- Diagnostics: For each cloud transcription we keep a small technical record — how long it took, which speech model ran, which device and app version were used, and an error code if it failed. This is used only to fix problems and improve speed. It never contains audio or text.
2. What We Don't Collect
- We do not store your audio recordings.
- We do not store your transcription text on our servers.
- We do not sell or share your data with third parties.
- We do not use your data for advertising.
3. Local Storage
The desktop app stores the following data locally on your computer:
- Settings and preferences
- Personal vocabulary (learned words and corrections)
- Word Bank rules and templates
- Transcription history
This data stays on your device unless you choose to export it.
4. Third-Party Services (Sub-processors)
VoltType uses the following third-party services to process your data. All are located in, or process data in, the United States.
- Groq: Speech-to-text transcription and AI text cleanup. Audio is sent for processing and is not retained by us. Subject to Groq's Privacy Policy.
- Supabase: Account authentication and usage records. Subject to Supabase's Privacy Policy.
- Cloudflare: Website and API hosting, and cookieless website analytics on volttype.com — page counts only, no cookies, no client-side storage and no cross-site tracking, which is why this site has no cookie banner. Subject to Cloudflare's Privacy Policy.
- Stripe: Payment processing for paid plans. We never see or store your card details. Subject to Stripe's Privacy Policy.
- Resend: Sending account and service emails. Subject to Resend's Privacy Policy.
- GitHub: Hosting the application installer you download. Subject to GitHub's Privacy Statement.
International transfers. If you are in the EU/EEA or UK, your data is transferred to the United States. These transfers rely on the Standard Contractual Clauses and equivalent safeguards offered by each provider above.
Offline mode (Windows and Android, Pro). When you use Offline mode on VoltType, your audio is processed entirely on your own machine and is not sent to Groq or to us at all.
4a. The AI in VoltType
Where the AI runs and what it sees →
VoltType uses AI to turn speech into text, to work out who spoke, and to write summaries, to-do lists and drafts from your own words. In plain terms:
- On your device. With the offline packs, recognition and writing happen on your own phone or PC. Nothing is sent anywhere. You can check this yourself — the app’s Data log lists every request it makes, and during an offline dictation it stays empty.
- In the cloud. Without the packs, audio and the text you ask about go to the sub-processors named in section 4, are processed in memory, and are deleted immediately. They are never stored by us and never used to train any model.
- We do not build models. We use published models as they are. Nothing you say is used to train or fine-tune anything.
- AI gets things wrong. Recognition can mishear a word, and a summary is a draft, not a record. Read it before you rely on it. We never use AI to make a decision about you.
- We do not detect emotion — not now and not later. VoltType does not judge mood, stress, health or character from a voice. This is a permanent design rule, written into our own AI Act assessment.
4b. Voices You Name (Meetings)
If you type a person’s name next to a speaker in a meeting, VoltType can keep a voice fingerprint so your next meeting recognises them.
- A fingerprint is a list of numbers. It contains no audio, and it cannot be turned back into a voice or into words.
- It is stored only on your own device. It is never sent to us. We never see it, hold it, or back it up.
- A voice fingerprint is personal data belonging to the person whose voice it is, and under EU law it is a special category. The app therefore asks you to confirm that the person agreed before it saves anything. Please actually ask them.
- You can delete any saved voice with one tap, at any time, in Meetings.
Recording people. VoltType records only when you press record. Everyone in the room must know and agree. In some countries — Germany and France among them — recording a conversation without everyone’s agreement is a criminal offence. The app reminds you before your first recording; asking the room is the part only you can do.
5. Why We Process Your Data (Legal Basis)
If you are in the EU/EEA or UK, the GDPR requires us to tell you our legal basis for each use of your data:
- To provide the service (account, transcription, sync) — performance of our contract with you.
- To take payment — performance of our contract with you.
- To keep the service secure and prevent abuse (rate limits, quota records) — our legitimate interests.
- To send you product or feedback emails — your consent, which you can withdraw at any time by replying "unsubscribe".
- Voice fingerprints you choose to save — explicit consent: yours, and that of the person whose voice it is. Stored on your device only; we never receive it.
6. How Long We Keep It
- Audio recordings: not retained. Audio is processed and discarded; we never write it to storage.
- Transcribed text: not retained on our servers. Your history is stored locally on your own device.
- Account details (email, plan): kept for as long as your account exists.
- Usage records (timestamps, seconds and word counts — not content): kept while your account exists, so we can apply the free plan’s monthly word quota.
- Payment records: retained by Stripe for as long as the law requires them to keep financial records.
When you delete your account, your account details and usage records are deleted with it.
7. Data Security
All data transmitted between the app and our servers is encrypted using TLS. API keys and secrets are stored securely and never exposed to client-side code. Sign-in tokens on your device are stored in the operating system's encrypted storage.
8. Your Rights
If you are in the EU/EEA or UK you have the right to access your data, correct it, delete it, receive a copy in a portable format, object to or restrict processing, and withdraw consent at any time.
To exercise any of these, email [email protected]. We will respond within 30 days, and there is no charge. We do not yet offer a self-service export button — ask us and we will send your data to you.
You can delete your account and all associated data at any time by contacting us at [email protected]. Your local data can be deleted by uninstalling the app.
Data kept on your own device — your notes, meetings and any saved voices — is deleted by deleting it in the app or uninstalling. We cannot delete it for you, because we never have it.
If you believe we have handled your data improperly, you have the right to complain to your national data protection authority.
9. Data Controller
The data controller for VoltType is Djoko Chrchev, contactable at [email protected]. VoltType is operated from Copenhagen, Denmark. See also the Legal Notice (Impressum).
10. Children
VoltType is not directed at children under 16, and we do not knowingly collect their data.
11. Changes
We may update this policy from time to time. We will notify you of significant changes via the app or email.
