ToS Clarification: Storing Lat/Long and Address from Places Autocomplete vs. User-Confirmed Map Marker

by

Summary

The Google Maps Platform Terms of Service (ToS) have specific guidelines regarding data storage, particularly for Latitude and Longitude coordinates obtained through Places Autocomplete or User-Confirmed Map Marker. The main concern is whether storing these coordinates indefinitely is permitted, especially when considering user-provided data and user-confirmed data.

Root Cause

The root cause of the confusion lies in the interpretation of the Google Maps Platform Terms of Service, specifically:

  • Section 3.2.3: No Scraping and No Caching rules
  • Maps Service Specific Terms: caching restrictions and exemptions
    The key issue is determining whether user interaction (e.g., selecting an address or confirming a map marker) transforms API-provided data into user-generated or user-confirmed data, allowing for permanent storage.

Why This Happens in Real Systems

This issue arises in real systems due to the following reasons:

  • Misinterpretation of ToS: developers may not fully understand the caching restrictions and exemptions
  • Lack of clear guidance: official documentation may not provide explicit examples or clarification on user-confirmed data
  • Desire for data persistence: developers want to store user-verified data indefinitely, avoiding the 30-day refresh cycle

Real-World Impact

The real-world impact of non-compliance with the ToS can be significant, including:

  • Account suspension or termination
  • Financial penalties
  • Reputation damage
  • Loss of access to Google Maps services

Example or Code

# Example of storing user-provided address string
def store_user_address(address_string):
    # Store the address string in the database
    user_address = UserAddress(address_string=address_string)
    user_address.save()

# Example of storing user-confirmed coordinates
def store_user_confirmed_coordinates(lat, lng):
    # Store the coordinates in the database
    user_coordinates = UserCoordinates(lat=lat, lng=lng)
    user_coordinates.save()

How Senior Engineers Fix It

Senior engineers address this issue by:

  • Carefully reviewing the ToS: ensuring a deep understanding of the caching restrictions and exemptions
  • Seeking official guidance: contacting Google support or consulting with experts to clarify any doubts
  • Implementing compliant solutions: designing systems that adhere to the ToS, using user-provided data and user-confirmed data correctly
  • Regularly auditing and updating: ensuring ongoing compliance with the ToS and adapting to any changes or updates

Why Juniors Miss It

Junior engineers may miss this issue due to:

  • Lack of experience: limited familiarity with the ToS and caching restrictions
  • Insufficient training: inadequate guidance on compliant data storage and handling
  • Overemphasis on functionality: focusing on implementing features without considering the ToS implications
  • Unclear documentation: difficulty understanding the official documentation and guidelines
