Import and Export

Content

⚠️ Do not close Slek during import or export. You can continue to use the application by letting the operation run in the background, but avoid refreshing the page.

How to Import?

For the import to go as smoothly as possible, proceed in this order:

make sure you have properly configured:
- your custom daily data if there are any in the file to import (otherwise, they will simply be ignored)
- your training zones
import your daily data (so that the zone calculation over time uses the correct HR max, FTP, etc. values...)
import raw (FIT) data in ZIP format (once training zones are known - see below)
import activity data in CSV format (which will then attach to already imported raw data)

Importing your library of workouts is not linked and can be done whenever you want.

Import Formats

Detailed formats are described here.

Bulk Import of FIT Files

Depending on the source of your data (partner platforms), you can do direct import (without going through files) on the Data Synchronization page or go through ZIP files of FIT files.

From Suunto, you can retrieve your entire history by direct import.
From Garmin Connect direct import is limited to 5 years. If you want to retrieve a complete history, you will need to request a bulk export unzip it, and come import here the ZIP files you'll find in the DI_CONNECT > DI-Connect-Uploaded-Files folder.
Coros allows direct import of the last 3 months only, but if you request a bulk export Slek will know how to import it and you'll have your entire history.
For Polar, it's more complicated. They don't allow direct import of your history at all. In addition, if you request a bulk export of your data, they are not in standard FIT format. You therefore only have the option of going through Strava's bulk export if your activities were synchronized there (or any other equivalent service providing an export in the form of FIT files).

Data Export

Everything you enter in Slek belongs to you. In accordance with its privacy policy and GDPR (General Data Protection Regulation), you have a right to portability of your data.

You can therefore export:

In ZIP format, all your raw data, i.e. FIT files generated by your cardio/GPS devices
In spreadsheet CSV format, all data associated with your activities (feelings, targets of planned sessions, if applicable corrected values, ...)
In spreadsheet CSV format, all daily data you have entered in Slek (morning checkup, ...)
In ZIP format, your workout library (the ZIP contains a CSV with the description of workouts as well as all attachments associated with these workouts)

NB: in some cases, ZIP generation can be quite resource-intensive for Slek. To avoid cyber-attacks you cannot request the same ZIP more than once per week.
