The short version
- Your videos and audio are processed on your iPhone. We never receive them.
- There is no account, no analytics SDK, no advertising and no cross-app tracking.
- Apple processes payments. RevenueCat checks whether you own Pro.
- This website sets no cookies and runs no analytics.
- The only personal data we keep ourselves is an email you choose to send us. Purchases are handled by Apple and RevenueCat.
Who we are
Louden is an iPhone app developed and operated by an independent developer. In this policy, “Louden”, “we”, “us” and “our” mean the developer of the app. You can reach us at hello@leesnu.app.
For the purposes of the EU and UK General Data Protection Regulation, we are the data controller for the limited processing described below.
Your media
Louden reads only the file you choose, from Photos, Files or the iOS share sheet. The audio is decoded, boosted and encoded on your iPhone. The louder copy is saved where you choose, in Photos or Files.
We do not upload, copy, transmit or retain your media on any server. There is no media storage on our side. Your original file is never modified.
The app may create temporary working files while an export runs. They are removed when the export finishes or when the app cleans up, and they are never sent anywhere.
What is stored on your device
Louden keeps a small amount of information locally so it works the way you expect:
- your settings, such as limiter and effect preferences;
- the number of free exports you have used today;
- a cached copy of your Pro status, so a purchase is not lost when you open the app offline.
This data stays in the app’s local storage and is removed when you delete the app. A cached Pro status is cleared when the store confirms that Pro is no longer active.
If you use iCloud Backup or a computer backup, iOS may include Louden’s local data in that backup. Those backups are controlled by you and Apple, not by us.
Purchases and RevenueCat
Purchases are processed by Apple. We never see your payment card, billing address or Apple ID password.
To unlock Pro and restore purchases, Louden uses RevenueCat, Inc. When you open the app or buy something, RevenueCat may receive:
- an anonymous app user ID generated for your installation;
- the App Store receipt and transaction details, including the product purchased and entitlement status;
- basic technical information such as platform, operating system, app version and country;
- your IP address, which is part of any network request.
RevenueCat does not receive your name, email address, contacts or media. We use this information to validate purchases, restore them, prevent fraud and understand aggregate, non-identifying sales trends. We do not sell it and we do not use it for advertising.
Apple and RevenueCat process this data under their own privacy policies. See Apple’s Privacy Policy and RevenueCat’s Privacy Policy.
Update checks
Louden uses Expo Application Services to check for and download JavaScript updates. Those requests include technical information such as your platform, app version, runtime version and IP address. They do not include your media or your purchase details.
This website
This is a static website hosted by Vercel. It sets no cookies, runs no analytics and loads no third-party scripts or fonts.
Vercel processes standard request logs — IP address, browser user agent, requested page and timestamp — to deliver the site and protect it from abuse. Our fonts are served from this domain, not from Google.
What we do not collect
We do not ask for or collect:
- your name, email address or phone number, unless you email us first;
- your contacts or precise location;
- camera or microphone access;
- the photos, videos or audio you choose — they stay on your device;
- advertising identifiers or cross-app tracking data.
Louden has no login, no social features and no advertising. We do not build a profile of you.
Legal bases (EEA and UK)
If you are in the EEA or the UK, we rely on:
- Performance of a contract — to provide Pro and process your purchase.
- Legitimate interests — to keep the app and website secure, prevent fraud and understand aggregate sales. We balance these interests against your rights.
- Legal obligation — where we must keep records.
We do not rely on consent for any processing, and we do not send marketing email.
How long we keep data
- Media: not stored by us at all.
- Local app data: until you delete the app.
- Purchase and entitlement records: held by Apple and RevenueCat under their retention policies. We keep only aggregated, non-identifying sales totals.
- Emails you send: for as long as needed to resolve your request, then deleted — normally within 24 months.
- Website logs: retained by Vercel for a short period under its policy.
Your rights
Depending on where you live, you may have the right to access, correct, delete, restrict or port your personal data, or to object to processing. You can also lodge a complaint with your local data protection authority.
Because Louden has no account, we may not hold information that identifies you. If you have emailed us, we can find and act on that. To make a request, email hello@leesnu.app. We respond within the time required by law, usually within 30 days.
If your request concerns purchase data held by RevenueCat, we will pass it on or tell you how to contact them.
US privacy rights
If you live in California or another US state with a comprehensive privacy law, you may have the right to know, access, correct or delete personal information, and not to be discriminated against for exercising those rights. We do not sell personal information and we do not share it for cross-context behavioural advertising. To make a request, email hello@leesnu.app. We may need to verify your request, but because we do not hold account data, we often cannot link information to you.
Children
Louden is not directed to children. We do not knowingly collect personal data from children under 13, or under 16 in some countries. If you believe a child has sent us personal data, contact us and we will delete it.
Security
Media processing happens on your device. Purchase validation uses encrypted connections. No system is completely secure, but we keep the data we handle to the minimum needed to run the app.
Changes to this policy
We may update this policy when the app or the law changes. The date at the top shows the latest version. If a change is material, we will mention it in the app or on this page before it takes effect.
Contact
Email hello@leesnu.app. We usually reply within two business days.
