How Storage Cost Is Calculated
Sovereign and HighRisk both include 1 GB of cloud storage and 2 access keys, with a base usage rate of 2.5 credits per month. One credit has a base value of US$1. Storage accounting uses 1,073,741,824 bytes per GB.
Monthly usage rate
The monthly equivalent is:
2.5 credits
+ max(0, stored bytes / 1,073,741,824 - 1) credits
+ max(0, registered access keys - 2) × 2 credits
Storage beyond the included allowance is proportional to recorded usage, not rounded up to a whole GB. It includes the encrypted data counted by the service. Locally downloaded encrypted files do not incur cloud-file storage charges for their local contents; records retained in the Safe still count.
Examples before taxes or promotions:
| Cloud usage | Access keys | Monthly equivalent | Cost for 12 months at unchanged usage |
|---|---|---|---|
| Up to 1 GB | 2 | $2.50 | $30 |
| 2 GB | 2 | $3.50 | $42 |
| Up to 1 GB | 3 | $4.50 | $54 |
| 2 GB | 3 | $5.50 | $66 |
Agent Keys count toward the same access-key allowance and the 10-key maximum. Both current tiers use the same formula.
Credits and expiry
Prepaid credits are converted into remaining Safe time using the current usage rate. Adding chargeable storage or keys can shorten the expiry date; reducing chargeable usage can extend it. Reducing the recorded size of an archive also applies a small time charge (four hours under the current configuration), so deletion does not always produce the full increase suggested by the storage reduction alone.
Monitor the usage and expiry shown in the app, especially after uploads or key changes. Subscription calculations also take usage into account; review checkout and renewal totals. A per-month usage rate is not a monthly subscription offer: new subscriptions renew yearly.
Keep credits available before expiry. There is no lossless automatic free-plan fallback. See How Payments Work.
