Speak Natural processes information to provide language practice, account and purchase recovery, paid content delivery, and hosted AI allowances. Features and controls described below depend on the app version you use. You can always contact us by email, including if your version does not show a deletion control.
Speech and conversations. When you use practice features, recorded speech is sent for transcription, conversation text is sent to a language model, and text is sent for speech playback. Hosted mode sends requests through our backend to OpenAI. BYOK mode sends requests using your configured provider credentials. The current app uses Luna for text generation and evaluation, Whisper for transcription and OpenAI speech playback. Provider policies govern their processing and retention. Our backend processes request content in transit; its application logging avoids recording request bodies. This is not a promise of zero retention by every provider.
On your device. The app stores conversation history, learning progress, room settings and downloaded curriculum locally. API credentials use Android EncryptedSharedPreferences backed by Android Keystore. The Room learning database is app-private storage; it is not itself an encrypted database. Temporary recordings and playback chunks are deleted after processing/playback, with abandoned app audio cleaned at the next process start.
Accounts, purchases and hosted usage. Google/Firebase provides guest or Google sign-in identities, including the account ID and Google-provided email, name and profile photo URL where supplied. RevenueCat and Google Play handle purchase verification. Our backend stores account identifiers, purchase/access information, starter-pack choice, subscription allowance windows, usage reservations and recovery/audit records needed to provide and protect these services. Signing out does not erase these records or cancel Google Play subscriptions.
Analytics. Firebase Analytics receives app-interaction and learning level-completion events, device app-instance identifiers, session/lifecycle and purchase events, and approximate location derived from network addresses. The release disables advertising-ID collection and ad personalization signals and does not request advertising-ID/attribution permissions. Current Analytics settings retain event data for 2 months and user data for 14 months, with the user-data period reset by new activity. These settings do not apply to all aggregated reporting. Account deletion and analytics deletion are separate provider actions; where available, include the device references from Settings > Delete account and data so we can locate associated analytics records.
Backup and recovery. Android may back up learning history, progress, study selection and curriculum. Supported cloud backups require encryption capabilities; Android 8 devices keep this data local. API keys, sign-in state, cached purchase access and device-specific jobs are excluded. You must sign in and verify purchases again after restoring. Platform backup settings, timing and quota apply. Account sign-in does not provide cross-device learning-progress synchronization.
Your controls. Microphone permission controls recording, and notification permission and reminder preferences control study reminders. You can edit/remove BYOK credentials in Settings. Clearing app storage or uninstalling removes local app data, subject to separately retained Android backups. This does not erase server account/purchase records or cancel a subscription.
Account/data deletion and contact. Request deletion of your Speak Natural account and associated personal data by emailing tyuschak@tysci-eng.com from the Google email you use to sign into the app. Use the subject “Speak Natural account and data deletion.” We will match your account and ask you to confirm the request. If you no longer have access to that email, contact us to discuss other ownership verification. Never send passwords or Google verification codes. Within 30 days after verifying ownership, we delete the account data we manage and submit deletion requests to our service providers. Associated personal data is deleted by default. We keep verification and completion correspondence for 90 days after fulfillment to handle follow-up or disputes, then delete it. This does not extend the deletion period for account, starter-choice or usage data. Our service providers and Google Play control their own processing, backup and payment-record retention under their policies; submitting a deletion request does not mean all provider copies disappear immediately. We explain any remaining limitations when responding to your request.
Deleting an account does not cancel Google Play subscriptions or automatically issue a refund. Manage subscriptions at https://play.google.com/store/account/subscriptions. You may request deletion without cancelling. Account-linked starter choices and recovery information will be removed. Google Play order records are separate. If you return, restoring purchases may recover eligible store purchases; deleted learning records and account-linked starter choices are not promised to return.
To remove local history, progress, downloaded packs, settings and saved API keys, use Settings → Clear data on this device. This signs you out of the app and closes it; Android permissions must be granted again. Repeat on other devices as needed. This does not delete server accounts, subscriptions or existing Android backups.
Website waitlist. The iOS email waitlist is no longer active. If you previously provided an email for it, you may request deletion of any retained subscription record by contacting tyuschak@tysci-eng.com. Those records were processed using MailerLite; closing the waitlist does not itself establish that past records were deleted.
