Cancellation Natural Cycles: Easy Method
What is Natural Cycles
Natural Cycles is a fertility-awareness app that uses algorithmic analysis of basal body temperature and cycle data to provide fertility insights, contraceptive guidance, and cycle tracking. It is distributed as a digital subscription through app stores and directly via the Natural Cycles website, and the company also sells physical items such as basal thermometers and wearables in its webshop.
How to cancel Natural Cycles
- App Store (Apple): Open your Apple ID settings → Subscriptions → Natural Cycles → Cancel. You must cancel at least 24 hours before the renewal date. See the Natural Cycles help article: How to cancel a subscription.
- Google Play: Manage subscriptions in your Google Play account (Play Store → Subscriptions → Natural Cycles). Natural Cycles’ help pages do not document a dedicated Play-step-by-step, but subscriptions are generally managed via Google Play - cancel there at least 24 hours before renewal. See the cancellation help article: How to cancel a subscription.
- Web (direct via Natural Cycles site): Log in to your account at the Natural Cycles website → Manage Account → Billing → Plan → Cancel current subscription. Cancelling must be done at least 24 hours before renewal to avoid an automatic charge. See: How to cancel a subscription.
- Important: Deleting the app from your device does NOT cancel your subscription. You must cancel via the App Store, Google Play, or your Natural Cycles account as above.
What happens when you cancel
When you cancel a subscription, it will generally remain active until the end of the paid billing period; you will retain access to the app’s subscription features until that date. Cancellation prevents further automatic renewals. Your account data normally remains stored with Natural Cycles so you can re-subscribe later without losing historical entries, but you should review account or privacy settings in the app or on the website if you wish to delete personal data.
Will I get a refund?
For digital subscriptions, Natural Cycles’ policy states that all subscription purchases are final and refunds are not provided because subscriptions grant instant access to a medical-device service. For webshop physical items, Natural Cycles allows returns within 14 days of receipt if items are unopened, undamaged and in original packaging, with certain items (for example ovulation tests and intimate goods) marked as non-returnable. Defective physical products are eligible for return or refund outside standard return windows; the customer may need to provide evidence of the defect and may initially cover return shipping unless the defect is proven. For full details see the subscription and shipping policy: Subscription & refund policy and Shipping information.

Your consumer rights in Canada
Canadian consumers commonly have a 14-day right of withdrawal for many online purchases, but this statutory right does not typically apply to digital subscriptions that provide immediate access to a service - Natural Cycles explicitly does not offer refunds for subscription purchases for that reason. Physical goods sold through the Natural Cycles webshop are subject to return rules: unopened, undamaged items in original packaging can be returned within 14 days unless expressly excluded (for example, certain intimate or sanitary items). Defective products remain covered by consumer protection and warranty rules in Canada; if a product is defective you may be entitled to a repair, replacement or refund under applicable laws.
Customer experiences
Reviewers report a mix of positive and negative experiences. Many users praise the app’s ease of use, educational content, and integrations with wearables (Apple Watch, Oura, etc.), and find it empowering for understanding menstrual cycles. On the negative side, several users have complained about unexpected automatic subscription renewals and limited or slow customer support when addressing billing issues. Canadian customers have also reported surprise duty or import fees for hardware shipments (for example the NC Band) and occasional shipping delays or problems with webshop customer service.
Documentation checklist
- Account email and username used with Natural Cycles
- Order number or receipt for the subscription or webshop purchase
- Receipt/source of purchase (Apple App Store, Google Play, NaturalCycles website)
- Next scheduled renewal date and screenshots of subscription page if available
- Photos of product, packaging and any defect for webshop returns
- Shipping tracking number and customs/duty receipts if applicable
- Copies of any correspondence with Natural Cycles support and relevant help-article links
- If sending legal notice: printed copy, tracking/receipt for certified mail
Common mistakes
Users commonly make avoidable errors such as assuming deleting the app cancels the subscription - this does not cancel billing. Waiting until the day of renewal can cause an unwanted charge because Natural Cycles (and app stores) typically require cancellation at least 24 hours before renewal. Cancelling on the wrong platform (for example in the app instead of through the App Store for an Apple subscription) can leave the subscription active. Expecting a refund for a digital subscription when policy states subscriptions are final is another frequent source of dissatisfaction. For hardware orders, not accounting for possible import duties or taxes can lead to unexpected charges on delivery.
Comparative recap
| Method | Refund | Difficulty |
|---|---|---|
| App Store (Apple) | No for subscriptions (purchases final per policy) | Low - Medium (cancel via Apple ID → Subscriptions; must allow 24+ hours) |
| Google Play | No for subscriptions (purchases final per policy) | Medium (manage via Google Play subscriptions; Natural Cycles does not list Play-specific steps) |
| Web (NaturalCycles.com) | No for subscriptions; physical items may be returnable per webshop rules | Low (cancel via Manage Account → Billing → Plan; follow webshop return instructions for products) |
| Certified mail / Legal notice | Depends on case (used for formal notices, not a refund method) | High (formal process; useful for disputed billing or legal notices) |
After cancelling
After you cancel, verify that your subscription status shows as cancelled in the App Store, Google Play, or your Natural Cycles account and keep confirmation screenshots or emails. If you purchased physical items and plan to return them, follow the webshop return instructions, keep tracking information, and retain original packaging. For questions or disputes, consult Natural Cycles’ help center articles: cancellation help (How to cancel a subscription), subscription & refund policy (Subscription & refund policy), and shipping information (Shipping information). If you need to escalate or serve a formal notice, use certified mail and keep proof of delivery.
