Parvia — Privacy Policy
Effective date: July 10, 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 has no user accounts, shows no ads, and does not track you across apps or websites.
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 only. We do not have a copy.
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:
Google Cloud Speech-to-Text — converts your speech to text.
Anthropic (Claude) — generates the tutor's conversational reply from that text.
ElevenLabs — converts the reply text into spoken audio.
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 attach your name, email, or an account to this audio because the app has no accounts.
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.
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. This never leaves your device through us. You can erase all of it at any time via Settings → Delete all my data.
A random device identifier
To protect the service from abuse and enforce fair-use limits, the app generates a random identifier stored on your device and sends it with requests to our backend. It is not linked to your identity and you can reset it by deleting the app's data.
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.
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.
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). Because we do not maintain accounts or server-side copies of your practice content, most of your data is under your direct control on your device. 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.
