# FAQ

<details>

<summary>Why do my results change slightly after I edit an input?</summary>

They should not change between identical runs: CRQ Pro uses a fixed random seed, so the same inputs always give the same results. If numbers moved, an input actually changed (possibly a linked component edited elsewhere) or the iteration count was changed in Settings.

</details>

<details>

<summary>Why is the mean (Expected Annual Loss) so much higher than the median?</summary>

Cyber loss distributions are heavily right-skewed: most years are quiet, a few are catastrophic. Rare huge losses pull the mean up while the median stays low. That gap is real information; it is why CRQ Pro reports both, plus tail percentiles.

</details>

<details>

<summary>How many iterations should I use?</summary>

50,000 (the default) is fine for day-to-day modeling. Use 100,000 or 250,000 when tail percentiles (P99) matter, for example for final report numbers. Use 10,000 only for quick rough drafts.

<details>

<summary>Can I use CRQ Pro on two computers?</summary>

One device per license key at a time. To move, go to **Settings > Application > License > Remove** on the old machine, then activate on the new one. Move your data by exporting a **backup** on the old machine and restoring it on the new one. See [Import, export and backup](/crq-pro/guides/import-export.md#moving-to-a-new-machine).

</details>

<details>

<summary>How do I back up my data?</summary>

Turn on **automatic backups** under **Settings > Application > Backup** and choose a folder (point it at OneDrive, Dropbox, or a network drive for an offsite copy). CRQ Pro then writes a full `.cqbackup` there on launch and daily. You can also **Export backup** at any time. This matters because your data on disk is encrypted with a key tied to this machine, a backup is the copy that survives a reinstall or a new machine. See [Data storage and security](/crq-pro/reference/data-security.md#backups).

</details>

<details>

<summary>Does CRQ Pro work offline?</summary>

Yes, for up to 14 days at a stretch. The app verifies your subscription online at launch; when the server is unreachable it runs on a 14-day grace period from the last successful check, with a badge showing days remaining. Reconnect and relaunch to reset it.

</details>

<details>

<summary>I deleted something by accident. Can I get it back?</summary>

Yes. Press **Ctrl+Z** to undo a recent deletion or edit. Otherwise, if it was a soft delete, open **Trash** at the bottom of the icon rail and restore it. Permanent deletes and **Empty trash** cannot be undone.

</details>

<details>

<summary>Does changing the currency convert my values?</summary>

No. Currency is a display label only. If you enter 500,000 with USD selected and switch to EUR, it displays as 500,000 EUR. Keep one currency per workspace to avoid confusion.

</details>

<details>

<summary>Where is my data stored, and is it safe?</summary>

In an AES-256-GCM encrypted file in your OS application data directory, with the key in your OS credential store. Nothing is synced to a cloud. See [Data storage and security](/crq-pro/reference/data-security.md).

</details>

<details>

<summary>How do I model the effect of a control or treatment?</summary>

Duplicate the baseline scenario, adjust the factors the treatment changes (for example, lower Vulnerability to reflect a new control, or lower Loss Magnitude for better response), and compare. The **Treatment Comparison Report** formalizes exactly this: a baseline plus named treatment options with risk-reduction deltas.
