Spam SMS Blocker: Filtr Privacy Policy

Summary

Filtr never sends your messages anywhere. Apple only passes texts from unknown senders to the filter, and Filtr decides on your iPhone using your rules. A short preview of each filtered message is kept on your device so you can review it.

This policy covers the Spam SMS Blocker: Filtr app for iPhone and iPad, published by mk0.net, an independent app studio. It is written from what the app actually does in its code. Questions: [email protected].

What we receive

Nothing. We have no accounts or servers for this app, and nothing you enter in it is sent to us.

What stays on your device

• Your rules, blocked senders, whitelist and settings are stored on this device.
• For each message Filtr sorts, it saves the sender, the first 200 characters, the category, the rule that matched and the time, on this device only. Up to 600 of these are kept.
• Counts per sender and per keyword are stored on this device for the statistics and widget.

We cannot see this data. It is not uploaded to us.

Permissions the app may ask for

• Notifications: Asked when you turn on a daily summary, tips or milestone notices. These are local notifications and never include message content from your inbox.

Every permission is optional and can be changed later in the iPhone Settings app. Features that need a permission you decline simply stay unavailable.

Data that leaves your device

The app talks to the following services. Each receives only what is listed, and only for the purpose shown.

• RevenueCat (subscription management): An anonymous app user ID and your subscription status, when the app checks, starts or restores your subscription. Nothing you enter in the app is sent. Their privacy policy.

Sensitive information

Message previews and sender numbers are private. They are stored only on your device, are never sent to a server and are not included in rule backups.

Purchases

Subscriptions are sold and billed by Apple through the App Store. We never see your name, Apple ID, card or payment details. The app checks your subscription status through RevenueCat, which receives an anonymous ID and your purchase status, not your identity.

Ads, tracking and analytics

No ads, no tracking across apps or websites, and no data sold. The app contains no analytics SDK.

Account

No account needed. You turn the filter on once in the iPhone Settings app under Messages, then Unknown & Spam.

Children

Spam SMS Blocker: Filtr is not directed at children under 13, and we do not knowingly collect personal information from children.

Keeping and deleting your data

You can delete rules and senders in the app. Rule backups do not include message previews. To stop filtering, turn Filtr off in the iPhone Settings app under Messages, then Unknown & Spam. Deleting Filtr removes all of its data from this device.

Your rights

Depending on where you live (for example under the GDPR, UK GDPR, CCPA or KVKK), you have the right to access, correct, export or delete your personal data. Because the app keeps your records on your own device, you can do most of this directly in the app or by deleting it. For anything else, or for data held by a service listed above, email [email protected] and we will help within 30 days.

Changes to this policy

If the app starts handling data differently, we will update this page and the date below before the change ships.
