Parvia — Privacy Policy
Effective date: September 15, 2026
Parvia ("we", "us") is a voice-based language practice app operated by Dewy Creative Group LLC. This policy explains what data the app handles and why. We built Parvia to collect as little as possible: Parvia shows no ads and does not track you across apps or websites. An account is optional — the app works fully without one, and you only have one if you choose to sign in.
Summary
Your practice audio is sent to speech-processing providers only to turn your speech into text and to generate your tutor's spoken reply. It is processed in real time and not used to build a profile of you.
Your saved vocabulary, streaks, and settings are stored on your device. If you choose to sign in, a copy is also saved to your account so your progress reaches your other devices. Without an account we have no copy.
Signing in is optional. If you sign in, we receive your email address and, where the provider supplies it, your name.
We do not sell your data or use it for advertising.
What we collect and how we use it
Microphone audio (processed, not stored by us)
When you start a conversation and speak, the app records short audio clips and sends them to our processing backend, which relays them to third-party services to make the app work:
ElevenLabs — converts your speech to text, and converts the tutor's reply text back into spoken audio.
Google Cloud Speech-to-Text — used as a backup for speech-to-text if the first service is unavailable.
Anthropic (Claude) — generates the tutor's conversational reply from that text.
These clips are processed transiently to provide the response and are not stored on our servers and not used to identify you or serve advertising. Each provider processes the data under its own terms and privacy policy. We do not store your practice audio, whether or not you have an account.
Text you enter
Optional scenario details you type on the setup screen (your role, the tutor's role, context) are sent with your conversation to generate relevant replies, and are handled the same transient way as above.
To make speech recognition more accurate, the app also sends a short list of words you are currently studying along with each recording, so the service is more likely to recognise them correctly. That list is used only to transcribe that recording and is handled the same transient way as above.
Data stored on your device
Your saved words, review history, streaks, and language preference are stored locally on your device using the app's on-device storage. You can erase all of it at any time via Settings → Delete all my data. If you are not signed in, this data never leaves your device through us.
Your account, if you create one (optional)
You can sign in with Apple or Google so your progress is saved and follows you to another device. This is entirely optional and the app is fully usable without it.
What we receive: your email address, and your name where the provider supplies it. We never see or store your Apple or Google password.
What we store: your learning progress — saved words and their review scheduling, lesson completions, practice scenarios you wrote, and your language and level preferences — linked to your account.
What we do not store: your practice audio, and any payment details.
Where it is stored: with our database provider, Supabase, which processes it on our behalf.
Deleting it: Settings → Delete account permanently deletes your account and everything saved to it. This cannot be undone. Deleting your account does not remove the copy on your device; use Delete all my data for that.
A random device identifier
To protect the service from abuse and enforce fair-use limits, the app sends an identifier with requests to our backend. When you are signed out this is a random identifier generated on your device and is not linked to your identity; you can reset it by deleting the app's data. When you are signed in, your account identifier is used instead.
What we do NOT collect
The app currently includes no analytics, no advertising SDKs, and no third-party tracking or crash-reporting tools. We do not request your contacts, photos, or location. We do not collect an email address or name unless you choose to create an account.
Subscriptions
Subscriptions are sold and processed by Apple (App Store) or Google (Google Play), not by us. Your payment details are handled by those platforms under their privacy policies; we receive only whether a valid subscription or trial is active. We use a subscription-management provider (RevenueCat) to check entitlement status.
Microphone permission
Parvia requests microphone access solely to record your speech during a practice conversation. You can revoke it at any time in your device settings; the conversation feature will not work without it.
Children's privacy
Parvia is not directed to children under 13 (or the equivalent minimum age in your jurisdiction), and we do not knowingly collect personal information from them.
Your choices and rights
Delete your data: Settings → Delete all my data removes everything stored on your device.
Delete your account: Settings → Delete account permanently deletes your account and all progress saved to it. This is irreversible.
Stop audio processing: deny or revoke microphone permission, or simply don't use the conversation feature.
Depending on where you live, you may have additional rights over personal data (for example, if you are a California resident, rights under the CCPA/CPRA). If you have not created an account, we hold no server-side copy of your practice content and your data is under your direct control on your device. If you have an account, you can delete it and everything in it from Settings at any time, or contact us with any request. This policy is governed by the laws of the State of Alabama, USA.
Changes to this policy
We may update this policy as the app evolves (for example, if we add analytics). We will change the effective date above and, for material changes, surface a notice in the app.
