| CAD geometry, shapes, dimensions, metadata | AI analysis of your sketch | Store and display your scan history | Contract performance |
| Original sketch photo | Your device camera / library | Temporary AI processing; stored locally on your device only, unless you request a human review (below) | Contract performance |
| Sketch photo, drawing, your note and any messages you exchange during the review — only when you request a human review | Sent by you when you ask our team to correct a result | So a member of our design team can see the sketch, correct the drawing, and answer any questions | Contract performance |
| Push notification token | Generated by your device when you request a human review | So we can notify you when a designer replies or your corrected drawing is ready | Contract performance |
| Subscription plan & scan count | App usage | Enforce plan limits and billing | Contract performance / Legal obligation |
| Anonymous usage statistics (app version, platform) | App operation | Improve app reliability and features | Legitimate interests |
| Data Type | Retention Period |
|---|---|
| Account information (email, name) | Duration of account + 30 days after deletion request |

| Sketch photos (local device storage) | Until you delete the part or uninstall the App — entirely on your device |
| Sketch photos sent to AI (Anthropic) | Processed transiently; not retained by Anthropic beyond the API request |

About the abuse-prevention record. The free plan includes a limited number of scans each month, and each scan costs us money to run. To stop the free allowance being reset by deleting an account and immediately signing up again with the same address, we keep a record that your address used its free scans in a given month. We store this as a one-way cryptographic hash — we do not keep your email address in this record, it cannot be reversed back into your address, and it contains nothing else about you or your designs. Because its only purpose is to remember that a free allowance was already spent, it is retained when you delete your account; deleting it with the account would defeat the point of keeping it. We rely on our legitimate interest in preventing abuse of the free tier (Article 6(1)(f) GDPR) as the lawful basis. Everything else tied to your account is deleted as described above.
About human review. Automated analysis is not always right. If a drawing comes out wrong, paid plans can ask a member of our design team to correct it by hand. This is the only situation in which your sketch photo leaves your device and is stored on our servers, and it only ever happens for a sketch you explicitly submit for review — we ask you to confirm this each time, and we never upload photos in the background. A named member of our team will look at that photo in order to redraw it. Any messages you exchange with them while the review is in progress are stored alongside it, so the conversation is there if you or the designer need to refer back to it. The photo is deleted 90 days after the review is finished, and immediately if you delete your account. We keep the before-and-after drawings and the conversation for longer, because comparing them is how we measure and improve the accuracy of the automated analysis; those records contain geometry and text only, with no photo. They are deleted along with everything else when you delete your account. If you enable notifications so we can tell you when a designer replies, your device registers a push token with us for that purpose only — it is never used for anything else, and is deleted along with everything else when you delete your account.
We share your data only with the following processors, each bound by a Data Processing Agreement (DPA):
Your data is processed on servers located in the United States (Supabase on AWS us-east-1; Anthropic; RevenueCat). If you are located in the European Economic Area (EEA) or UK, these transfers are made under Standard Contractual Clauses (SCCs) approved by the European Commission. By using the App, you consent to this transfer.
The App does not use browser cookies. The App does not currently use third-party analytics SDKs. If analytics are added in a future version, this Policy will be updated and you will be notified.
The App is not directed to children under 13 (or under 16 in the EEA). We do not knowingly collect data from children. If you believe a child has created an account, contact us immediately and we will delete the data.
We will notify you of material changes by updating the effective date above and, where required by law, by email or in-app notification. Your continued use of the App after changes constitutes acceptance.
