Privacy Policy
Last updated: · Effective:
Applies to Lingofy Stream website and Mac desktop application.
Lingofy Stream (“Lingofy Stream,” “we,” “us,” or “our”) provides a privacy-first Mac desktop application for local AI video dubbing and audiobook creation, together with a companion website for accounts, subscriptions, downloads, and support.
This Privacy Policy explains what information we collect, how we use it, when we share it, and the choices you have. It applies to our website, the Lingofy Stream desktop application, and related services (collectively, the “Services”).
By using the Services, you agree to this Privacy Policy. If you do not agree, please do not use the Services.
1. Privacy at a glance
Our product is designed so that your media stays on your Mac whenever possible.
- Video, audio, transcripts, voice samples, and exported files are processed and stored locally on your device by the desktop app.
- We do not upload your video or audiobook content to Lingofy Stream servers for translation or dubbing.
- Account, billing, license, and support data are handled by our website and payment partners so we can provide subscriptions and customer support.
- Some optional or fallback features (for example certain cloud text-to-speech voices, downloading a remote video URL you provide, or first-time model downloads) may use the internet.
2. Who we are
Lingofy Stream is a remote-first product serving users worldwide. For privacy questions, contact us at support@lingofy.stream.
Our primary website is https://www.lingofy.stream. The desktop app may also communicate with that site (or a configured equivalent) for license validation, downloads, release updates, and support requests.
3. What this policy covers
This policy does not cover third-party websites or services that you access on your own (for example a video hosting site whose URL you paste into the app), except where we describe how our Services interact with them.
- The Lingofy Stream website (accounts, pricing, downloads, contact, and related APIs).
- The Lingofy Stream Mac desktop application.
- Emails we send (for example one-time codes, purchase confirmations, and support replies).
4. Information we collect
4.1 Account and authentication information
When you create or sign in to a Lingofy Stream account on our website, we collect:
- Name and email address.
- Password (stored only as a secure one-way hash; we never store your plain-text password).
- One-time passcodes (OTPs) sent by email for signup, login, or password reset (stored temporarily in hashed form).
- A generated profile avatar URL.
- Session information (an access token and related account details kept in your browser’s local storage while you remain signed in).
4.2 Subscription and payment information
If you purchase a plan, we and/or our payment processor collect information needed to complete the transaction and activate your license, including:
- Plan selection, amount, currency, and purchase timestamps.
- Payment identifiers from our payment processor (for example order and payment IDs).
- Customer name and email associated with the purchase.
- An activation / product key we generate so you can unlock the desktop app.
- Subscription start and expiry dates.
4.3 Payment card details
Card numbers and other sensitive payment instrument details are collected and processed by our payment processor (Razorpay) in their checkout interface. Lingofy Stream does not store full card numbers on our servers.
4.4 License and desktop activation data
When you activate the Mac app with a product key, the app may send the key to our license validation API. In return, the app may receive and store locally:
- Whether the key is valid.
- Licensed user name, email, and avatar (if available).
- Subscription plan name and validity dates.
- Limited payment/history metadata associated with the license.
4.5 Support and contact information
If you contact us through the website or in-app contact form, we receive the information you submit, such as name, email, reason, subject, and message. We use this to respond to your request. Contact messages are delivered by email to our support inbox; they are not stored as a permanent customer database record in our application database.
4.6 Desktop app local data (on your device)
The desktop app stores operational data on your Mac (for example under Application Support for Lingofy Stream), which may include:
- Downloaded AI/runtime components (for example app-managed Python, media tools, and model files).
- Cached videos, transcripts, segment files, voice references, and exported dubbed videos or audiobooks.
- Setup completion flags, backend logs, and local configuration.
- Browser/local storage values for onboarding status, license cache, recent projects, and pipeline preferences.
4.7 Technical and usage information
We may receive limited technical information when you use our website APIs or update endpoints, such as request metadata needed to operate the service (for example app version or platform when checking for updates). We do not operate third-party advertising analytics trackers on our website.
4.8 Information we do not collect from media processing
We do not collect the contents of your uploaded videos, audiobook source text, generated transcripts, or dubbed audio as part of a Lingofy Stream cloud media-processing pipeline. Those workflows run on your device.
5. How we use information
We do not sell your personal information.
- Provide, operate, and improve the Services (accounts, subscriptions, downloads, activation, and support).
- Authenticate users, send OTPs, and secure account access.
- Process payments, issue activation keys, and manage subscriptions.
- Respond to contact and support requests.
- Send transactional emails related to your account or purchase (for example verification codes and order confirmations).
- Deliver desktop download links and release/update metadata.
- Detect, prevent, and investigate fraud, abuse, or security incidents.
- Comply with legal obligations and enforce our terms.
6. Local processing in the desktop app
Lingofy Stream is built around on-device processing:
- Speech recognition, translation, voice cloning / synthesis (where available on your machine), and export typically run locally after required models and dependencies are installed on your Mac.
- Your project files remain in local cache and export folders unless you copy or share them yourself.
- Internet access may still be required for: signing in / activating a license, downloading the app or updates, first-time downloads of models and tools, fetching a remote video URL you provide, optional cloud text-to-speech fallbacks (such as Microsoft Edge neural voices when that path is used), and submitting support messages.
9. Data retention
If you delete your account through the website account deletion flow, we remove associated user, OTP, payment, and subscription records from our application database. Payment processors and email systems may retain records independently as required by their policies or law.
- Account data is retained while your account remains active.
- OTP challenges are temporary and expire after use or timeout.
- Payment and subscription records are retained as needed for billing, license validation, accounting, and legal compliance.
- Support emails are retained in our email systems according to ordinary business email practices.
- Local desktop caches, exports, and logs remain on your device until you delete them or uninstall the app and remove Application Support data.
10. Security
We use administrative, technical, and organizational measures appropriate to the nature of the data we handle, including hashed passwords, encrypted transport (HTTPS) for website and API traffic, and scoped access to production systems.
No method of transmission or storage is completely secure. Please protect your account credentials and product key, and keep your Mac and the app up to date.
11. International users
We operate as a remote-first service and may process information in countries other than where you live. Where we do so, we take steps designed to protect personal information in accordance with this Privacy Policy and applicable law.
12. Children’s privacy
The Services are not directed to children under 16 (or the minimum age required in your jurisdiction). We do not knowingly collect personal information from children. If you believe a child has provided us personal information, contact support@lingofy.stream and we will take appropriate steps to delete it.
13. Your rights and choices
Depending on where you live, you may have rights to access, correct, update, delete, or export certain personal information, or to object to or restrict certain processing. You can:
- Review and manage account details while signed in.
- Request account deletion through the account deletion feature (where available) or by emailing support@lingofy.stream.
- Stop using the desktop app and delete local Application Support / cache data on your Mac.
- Contact us to ask questions or exercise applicable privacy rights.
We may need to verify your identity before fulfilling certain requests. Some information may be retained where legally required (for example transaction records).
14. Third-party services
Our Services may link to or integrate with third parties, including payment checkout, avatar generation, font delivery, installer hosting, and (in the desktop app) optional cloud TTS or model download sources. Their privacy practices are governed by their own policies. We encourage you to review them.
15. Changes to this policy
We may update this Privacy Policy from time to time. When we do, we will revise the “Last updated” date above and, where appropriate, provide additional notice. Continued use of the Services after an update means you accept the revised policy.
