Privacy Policy
Lightning Log, an Alexa skill. Effective November 11, 2026.
What the skill uses
Your device address, if you allow the Alexa "device address" permission. The skill uses it only to find the map location to check for lightning. It sends the address to the U.S. Census Bureau geocoder to get coordinates, and does not store the address itself.
A ZIP code, if you say one instead. The skill uses the center of that ZIP code.
What the skill stores
Linked to the anonymous user ID that Alexa assigns for this skill: the coordinates of your location rounded to three decimal places (about 100 meters), a one-way hash of your address so the skill can tell when it changes without keeping it, and the ZIP code if you gave one. This is kept in the skill's database on Amazon Web Services until you delete it.
The skill never receives your name, email address, contacts, or voice recordings. Your interactions with Alexa are handled by Amazon under Amazon's privacy notice; you can review and delete them in the Alexa app.
Who else sees what
- U.S. Census Bureau geocoder: your street address, to look up coordinates (only when it is new or has changed).
- The Lightning Log lightning server (lightning.hydrocomplete.com), operated by the same developer: your coordinates rounded to two decimal places (about 1 kilometer), each time you ask. The server uses them to find nearby lightning in NOAA's satellite data and does not log or keep them.
Nothing is sold, shared for advertising, or used to build a profile.
Deleting your data
Say "Alexa, ask Lightning Log to forget my location" to delete what the skill stored. To stop the skill reading your address, turn off the device address permission for Lightning Log in the Alexa app. You can also email the address below.
Purchases
Storm Tracker is a one-time purchase sold and billed by Amazon. The skill learns only whether your account owns it; it never sees payment details. To request a refund, say "Alexa, ask Lightning Log to refund Storm Tracker" or contact Amazon customer service.
Operational logs
Errors are logged by the skill's hosting (Amazon Web Services) for troubleshooting. These logs contain request types and error messages, not addresses or coordinates.
Children
The skill is not directed to children under 13 and does not knowingly collect information from them.
Changes
If this policy changes, the updated version will be posted at this address with a new effective date.
