What Keeping Records Safe Actually Looks Like
Injured people and families often keep copies of their materials in more than one place: the original on the phone, a copy in cloud storage, another on a separate device or drive, and printed copies of key documents such as medical bills and reports. For you, the stake is that a broken or lost phone does not have to mean lost evidence; if one copy disappears, the others remain.
Keeping files in their original format tends to protect the most information. A photo kept as the camera saved it, rather than converted, cropped or resized, keeps its metadata. A full message thread, exported or photographed screen by screen in order, shows more context than a single cropped screenshot.
Many people sort materials into folders by type, such as medical, photos, messages and work, and name files by the date of the event they show. A simple list of what exists and where each copy is stored can make the collection easier to follow.
A written account is one of the few records only you can create. People often write down what happened as soon as they are able: where they were, what time it was, what the lighting and entrances looked like, who was there, and what they saw, heard or were told, including anything said by staff or security. Noting the date the account was written shows how close in time it was made. The site's guide to preparing for your first consultation describes how such an account fits with other materials.
Not every item turns out to matter. A conversation with an attorney can help a person understand which of their materials bear most on the legal questions their particular situation raises, and which are background.
