Offline Maps Guide

Download map tiles to use without an internet connection.

Overview

Offline Maps is opt-in only. By default, Lens uses Apple Maps which keeps your map viewing private within Apple's ecosystem. If you need offline access, you can enable Mapbox-powered offline maps.

Privacy Notice: Enabling this feature shares data with Mapbox, a third-party service. You'll be asked for explicit consent before activation.

Enabling Offline Maps

Step 1: Access Settings

  1. Open Lens.
  2. Tap Settings (gear icon in the top left).
  3. Scroll to Offline Maps.

Step 2: Review Privacy Notice

When you first access Offline Maps, you'll see:

  • What data is shared: IP address, device info, approximate location (tile coordinates), session ID
  • Who receives it: Mapbox, Inc.
  • Link to Mapbox Privacy Policy

Step 3: Grant Consent

  1. Read the privacy notice carefully.
  2. Tap Enable Offline Maps to consent.
  3. Or tap Not Now if you prefer to keep map viewing private within Apple's ecosystem.

Method 2: Use Current Location

Problem: Selected area exceeds 6,000 tile limit.

Solution:

  1. Zoom in to reduce the area.
  2. Download multiple smaller regions instead.

"Storage full" error

Problem: You've reached the 1 GB storage limit.

Solution:

  1. Delete old maps you no longer need.
  2. Or clear all maps and re-download essentials.

Maps not appearing offline

Problem: Downloaded maps aren't showing when offline.

Check:

  1. Offline Maps enabled? Settings > Offline Maps
  2. Maps actually downloaded? Check DOWNLOADED MAPS section
  3. GPS signal? You need GPS to determine your location on the cached map

"Use Current Location" does nothing

Problem: Button doesn't respond.

Solutions:

  1. Location permission: Settings > Privacy > Location Services > Lens
  2. Internet required: Initial location lookup needs connectivity
  3. Try again: Close and reopen the Offline Maps screen

Frequently Asked Questions

Is my privacy protected if I don't enable Offline Maps?

Yes. By default, Lens uses Apple Maps which operates within Apple's ecosystem. No data is shared with Mapbox unless you explicitly enable Offline Maps.

Can I download the entire country?

No. Downloads are limited to prevent abuse and excessive storage use. Maximum is ~150-200 MB per region (6,000 tiles at zoom level 16).

Do downloaded maps expire?

No. Maps remain on your device indefinitely until you delete them or disable Offline Maps.

Can I download maps on Wi-Fi and use them on cellular?

Yes. Once downloaded, maps work without any internet connection (Wi-Fi or cellular).

Will this drain my battery?

No. Using cached offline maps actually reduces battery usage compared to live tile downloads.

Can I use offline maps for navigation?

Not currently. Offline Maps only provides static map tiles. GPS coordinates are still recorded on photos, but turn-by-turn navigation is not supported.
