We collect no personal data. Vela does not collect, transmit, or store on any server:
Vela stores the following data in a local SQLite database on your phone, accessible only to the Vela app:
| Data type | Purpose | Stored on |
|---|---|---|
| Cycle start and end dates | Cycle prediction | Your device only |
| Daily log entries (flow, symptoms, mood, pain, notes) | Symptom tracking | Your device only |
| Cycle length history | Prediction accuracy | Your device only |
| App settings | Personalisation | Your device only |
This data is never transmitted. It never leaves your device.
Vela is listed in the Health & Fitness category on both the App Store and Google Play. Both stores require us to explicitly disclose what health data the app does — and does not — access or collect.
Vela does not collect, transmit, or share any of the following:
Vela does not request permission to read or write to Google Health Connect, Google Fit, Apple HealthKit, or any other health data platform. No health data is ever transmitted from this app.
Vela does store reproductive health data, but exclusively on your device. This data is never transmitted anywhere:
| Health data type | Purpose | Collected or transmitted? |
|---|---|---|
| Menstrual cycle start and end dates | Cycle tracking and period prediction | No. On-device only. |
| Flow intensity logs | Daily symptom tracking | No. On-device only. |
| Symptoms (cramps, headache, mood, etc.) | Daily symptom tracking | No. On-device only. |
| Pain level and mood entries | Daily log | No. On-device only. |
| Freeform notes | Personal journal entries | No. On-device only. |
All data above is stored in a local SQLite database on your device. It is never uploaded to any server, shared with any third party, or linked to your identity in any way.
By default, Vela explicitly excludes its database from iCloud Backup (iOS) and Android Auto Backup. Your cycle data is not included in your device backup unless you manually change this in your phone's settings.
If you manually include Vela in your backup, your encrypted backup may contain Vela data. This backup is between you and Apple or Google — Vela has no access to it.
Vela uses local notifications to remind you of predicted periods and fertile windows. These notifications are:
Vela contains zero third-party SDKs. There are no integrations with:
The only network calls the app may make are to fetch the App Store receipt for purchase validation — a standard Apple/Google process that does not involve your health data.
Vela's app lock feature uses Face ID, Touch ID, or a PIN. Biometric authentication is handled entirely by the operating system. Vela does not access, store, or transmit biometric data.
Vela's optional disguise mode changes the app's display name and icon on your home screen. This feature is entirely local — no data is transmitted as part of this feature.
Vela is not designed for or marketed to children under 13 (under 16 in the EU/UK). We do not knowingly collect information from children. Since we collect no data from any users, this is moot — but we state it for completeness.
Vela does not process any personal data within the meaning of GDPR or UK GDPR, because no personal data is collected or stored on our systems.
If you are a UK or EU resident and believe we have processed your personal data, please contact us at support@cartolinks.com. We are required to respond within 30 days.
We do not sell personal information. We do not share personal information with third parties for cross-contextual behavioural advertising. We collect no personal information. CCPA rights therefore do not apply in a meaningful way.
We have no server-side copy of your data to act upon.
We may update this policy when the app is updated. The "last updated" date at the top of this page will change. Significant changes will be noted in the app's release notes. Continued use of the app constitutes acceptance.
