Absolutely not, so long as you have an active plan!
So long as you have an active plan (including the free plan), your songs will remain available across all digital storefronts. However, if you choose to delete your account then your songs may be taken down at our discretion.
If you want that extra reassurance, then select the "Permanent Release" add-on which can be found in the add-ons section when distributing your track. For a small one-off fee, we will ensure that your song is never taken down even if you delete your account or if we cease to operate.
